For a full list of new functionality and properties
implemented please visit :
http://www.steema.com/linkIn/WhatsNewAX2014
1) Polar, Radar and WindRose Series
New property ColorEachLine boolean property (default True).
When ColorEachPoint is True, ColorEachLine determines if lines connecting points will be also colored
segment by segment.

===============================================
17th June 2014
TeeChart Pro Activex Control v2014
v2014.0.0.1 Release
==============================================
New Features:
--------------------------
For a full list of new functionality and properties
implemented please visit :
http://www.steema.com/linkIn/WhatsNewAX2014
1) AskDelete property at IChartEditorOptions
which allows to specify if user have to
be asked before to remove a Series.
2) EditData property at IChartEditorOptions
which allows to specify if grid at
Data tab is readonly of not.
3) New Position property (Start, Center, End),
default = Center.
By default axis titles are positioned to the
middle of the axis.
Chart1.Axis.Bottom.Title.Position = tpStart
4) Chart Legend :
Important change: The Legend Symbol Squared property
is now TRUE by default. It was FALSE before. The
reason is cosmetic. Squared symbols look better in
more situations and different series styles,
than non-squared.
Chart1.Legend.Symbol.Squared = False
Series Transparency property is now used to display
Legend Symbols, in order to improve matching the
series format with the legend.
New Height and HeightUnits properties for Legend Symbol.
The vertical size of Symbols in Chart Legend can now be
specified in pixels or as a percentage of available space
(that depends on the size of the Legend Font).
5) Chart SeriesList :
New OnSeriesClicked method, returns the Series and the series
ValueIndex'th point that is under the XY pixel parameters:
ASeriesIndex = TChart1.SeriesList.Clicked( x,y, ValueIndex )
Returns “-1" if no point of any series contains XY.
One example of use is at MarksTip tool, this tool calls
SeriesList Clicked method to obtain which series is under
the mouse cursor.
6) New Filled property (boolean, default False)
for ContourSeries.
This property is equivalent to setting Brush.Style
= bsSolid, but more convenient and easy to remember.
TChart1.Series(0).asCountour.Filled = True
7) Bar and HorizBar Series
Improved detection in mouse xy Clicked method for 3D Bar cubes
and diamond styles. The algorithm now includes the bar cube
sides in 3D view (orthogonal and perspective).
8) Series Marks
New marks style “smsLabelOrValue”. This is now the default Style.
If Series point label text is empty, uses point value instead.
TChart1.Series(0).Marks.Style = smsLabelOrValue
New Automatic property (of type TAutomaticMarks)
Note: This property is not yet handled by all series styles. So far
it is used by Map and World series.
The intention of “Automatic” is to perform several attempts to avoid
series marks overlap other marks or other parts of the chart. It is
True by default in all subproperties.
Note: The existing AutoPosition property is now deprecated and mapped
to the Automatic.Move property.
Marks will be first repositioned to avoid overlapping. Its after auto
positioning when Automatic.Hide takes place if the mark still can't be
appropiately displayed.
Automatic.Resize means the series will try to reduce the mark font size
to fit the mark inside the available space, before deciding to hide the
mark completely.
Automatic.Wrap means to split the mark text into several lines of text,
to try to fit the mark.
Automatic.Rotate means to rotate 45 or 90 degrees the mark, as it can be
sometimes more convenient to fit more marks.
9) Custom Series
New InflateMargins boolean property (default True).
When False, Line or Area series will not try to expand the axes to
accommodate for the border size. This is more noticeable when the
TChart1.Series(0).asLine.Pen.Width is bigger than 2.
10)Series Pointer
New Pointer Arrow style (psArrow enum type):
TChart1.Series(0).Pointer.Style = psArrow
New Picture property (of type TTeePicture) to display an image at
pointer.
TChart1.Series(0).Pointer.Picture.LoadFromFile("Fire.png")
New public properties:
SizeFloat (Single)
SizeUnits (suPixels or suAxis)
SizeFloat allows specifying pointer size with more precision (with decimals),
while SizeUnits lets calculate pointer size using axes scales instead of screen
pixels.
This means, when “suAxis”, zooming a chart will also display zoomed pointers.
This feature is primarily used internally by TMapSeries.
11)Gauges
Improved display of less-than-360 degree Circular gauge Frame border.
Smooth painting of range color lines (with more precision and antialias).
New Hands collection property for Circular Gauge. More than one “Hand” can now
be displayed. Each hand has its own formatting and Value.
The previous “Hand” property is still supported, but now refers to Hands[0] item.
New Circular gauge Hand style: psArrow (draws an arrow head at Hand end position).
TChart.Series(0).asCircularGauge.Hand.Style = psArrow
New Ranges[] collection property for Linear, Knob and Circular gauges, allows more
than two colored segments inside the gauges. Existing “GreenLine” and “RedLine”
properties are still supported, but they now refer to Range[0] and Range[1].
Each Range now supports displaying normal or “spiralled” segments. Each Range now
includes a new Position property (% radius from gauge center), and StartValue and
EndValue properties to define the Range boundaries.
New AxisRanges[] collection property, allows drawing Axes in range segments.
Each “range” segment has Format properties.
Automatic calculation of gauge axis Increment (the step between gauge axis labels),
to avoid overlapping labels. Same as with normal charts, automatic Increment when its
zero.
Circular Gauge axis labels are now displayed using the Axis DrawAxisLabel method
instead of a simple Canvas Texout. This allows supporting all Axis.Texts formatting
properties, like background, shadow, etc.
Gauge editor dialogs have been modified to support editing (and adding, deleting)
multiple Ranges and Hands items at design-time and runtime.
CircularGauge Marks now supported.
Gauge Hand value can be displayed using the default Marks property, located below the
gauge center.
TChart1.Series(0).asCircularGauge.Marks.Visible := True
12)Canvas
Improved support for semi-transparent (alpha) PNG images, for both GDI and GDI+ canvases.
Transparent PNG pictures are now correctly blended with the background
(note: TChart1.BufferedDisplay property must be True).
This applies to both Canvas Draw and StretchDraw methods.
New CubeHull method returns the polygon that encloses a 3D cube. It is used by CustomBar
series (to detect mouse clicks on 3D bars with the Clicked method), and Canvas ClipCube
method to limit drawing outside the 3D “cube” delimited by axes.
New internal IsAvailable boolean class virtual function.
GDI+ canvas overrides this function, see Other Changes below.
GDI+ canvas now correctly displays flat shadows when any object's Shadow.Smooth property
is False.
TChart1.Legend.Shadow.Smooth = False
OpenGL canvas improved display of Pen Transparency. And better Zoom matching when switching
from a non-opengl canvas.
13)WorldMap Series
World and Map series “Layers”.
“Layers” concept for Maps can be easily implemented by using additional series. Each Layer
being a different Series, with its own properties, and painted one after the other over the
same chart.
Also, more than one Map or World series can be used and combined in the same chart.
With this new release, Map Layers get more useful as there are new methods to handle GIS file
formats like Google's Earth KML with placemarks, and ShapeFile files containing polylines (roads, etc).
World Country names have been augmented with country ISO 2-letter codes (ie: Canada=CA) Series Marks
can now display country names, codes, or both.
China, France, Japan county maps are now included. One polygon is used for each county / province.
New TeeFlags.res resource, contains all country flags pictures as small gifs. These flags can be used
in World series to display them inside each country polygon, and also at chart grid when visualizating
country data.
To enable showing flags, a new property is introduced:
TChart1.Series(0).Flags.Visible = True
17) Map Series
New IMapPolygon Code (string) property. This is an alternative string to Text property, and can be used
when displaying Series Marks inside the polygon.
New TTeePolygon Centroid function (returns TPoint). Centroid returns the XY point inside the polygon that
is best equidistant to all polygon points. This is different than the middle XY position of the polygon
bounding rectangle.
Centroid position is used when displaying text Marks inside the polygon.
New IMapPolygon Picture property (of type IBackImage). Allows filling the polygon interior using an image.
New ITeePolygonGroup class, allows creating logical groups of polygons (shapes) to change properties of all
items with a single group property. Groups are used for example by World series to keep together continent
countries or country states or provinces.
New Shapes.ByCode array property, returns shape that has a given Code:
tmp = TChart1.Series(0).asWorld.Shapes.ByCode['CA'] ; // Returns shape that corresponds to “Canada”
New MapMarks property. Contains properties to customize displaying series text marks inside polygons:
TChart1.Series(0).asWorld.MapMarks.AutoSize = False
AutoSize (boolean default True), fits text inside polygon by changing font size.
Centroid (boolean default True), positions text at polygon centroid instead of center of polygon rectangle bounds.
TextStyle (mtLabel, mtCode, mtBoth) choose which polygon text to display.
Uppercase (boolean default False), when True, show mark text in uppercase.
New Pointer property (TSeriesPointer) and PointSize (Single).
These properties enable Map series to display items as simple “pointer” shapes instead of polygons. It is useful
for example to display thousands of dots over a World map, being each dot an Airport or a City or whatever.
When Point size is zero (the default), size is automatically changed when zooming the map.
TChart.Series(0).asWorld.Pointer.Style = psCircle
Several optimizations in Map series intended to improve the painting speed when zooming or scrolling maps. Best
speed is achieved when using an OpenGL canvas.
18) 3D / Palette Series
Added CountLegendItems function.
Added LoadPaletteFromFile method.
Added SavePaletteToFile method.
Color palette for 3D series can now display custom Text at Legend (runtime only):
The Legend TextStyle property is used like in all other series styles to determine when to use this palette text:
TChart1.Legend.TextStyle = ltsLeftValue
19) Tower 3D Series
New Stacked property.
Like in TeeChart for .Net, multiple Tower series can now be displayed as stacked (one on top of another).
TChart1.Series(0).Stacked = tsStacked
20) Chart Tools
MarksTip tool new property SystemHints (boolean default True).
When False, a normal ITeeShape object is used to paint the tiptool instead of using the VCL system
mechanism.
TChart1.Tools.Items(0).asMarksTip.SystemHints = False
TChart1.Tools.Items(0).asMarksTip.Format.Font.Size = 24
TChart1.Tools.Items(0).asMarksTip.Format.Font.Color = vbBlue
The only disadvantadge compared to system hints is the shape cannot be displayed outside the chart bounds.
When SystemHints is False, the new Format property (of type ITeeShape) contains all the formatting properties
(Brush, Pen, Font, etc) to display the hint.
21) TBackImage
New property DrawQuality : EStretchDrawQuality (default value: sqHigh):
TChart1.Panel.BackImage.DrawQuality = sqLow
22) TSeriesMarks
New property UseSeriesTransparency : Boolean (default True)
When False, series marks will be painted using their own transparency, without accumulating the marks series
transparency, if any.
TChart1.Series(0).Marks.UseSeriesTransparency = False
23) All Series
New ISeries.Legend property of type ITextShape.
This new property includes a Picture property to display an image or icon for each series at the Chart Legend
Symbol.
Thanks to this new property, the existing ISeries.ShowInLegend is now equivalent to ISeries.Legend.Visible,
and ISeries.LegendTitle is the same as ISeries.Legend.Text.
24) IImagePoint and IDeltaPoint
Improved painting of legend symbols, these series now show the corresponding image for each point at the legend.
25) ColorGrid, Surface, TriSurface Series
Speed improvements, caching calculated values to avoid repeating and spending time at each repaint (like when
doing zoom and scroll).
Adding or modifying series point values empties the cache so it will be recalculated at the next repaint.
26) Bar and HorizBar Series
Cylinders are now painted filling them with gradients, instead of drawing “sides”.
The output is of much better quality (and speed), although currently there is no rotation of gradients when the
chart is rotated with 3D perspective.
The ConePercent property (from 0 to 100, default 0) is now published (it was public).
27) Contour Series
Null values (in grid cell data) are now supported. Contour levels will not use null data.
TChart1.Series(0).SetNull( 23 ) ' ? point index 23 is now null
28) Polar Contour Series
New series style to display contour lines from XYZ data using Polar (Angle and Radius) coordinates.
This series is derived from Polar series class (to draw circular background, axes, etc), and includes a Contour
series internal field (to calculate the contouring lines, customize contour levels, etc).
“X” indexes are converted to angles (from 0 to 360 degree). For example if the 3D grid has NumXValues = 10, then every angle interval will be 36.
“Z” indexes determine the radius, and the “Y” values are used to calculate the level lines.
Data can be manually added using the Series1.AddXYZ or AddNullXZ methods.
Typical settings for geographical data are to set 90 degree at top (North), and drawing labels clockwise (270 = West, 90 = East).
TChart1.Series(0).asPolarContour.RotationAngle=90
TChart1.Series(0).asPolarContour.AngleLabels.ClockWise=True
29) SeriesStats Tool
New method to remove (destroy) all series that have been created using the Series Stats tool editor dialog:
TChart1.Tools.Items(0).asSeriesStats.FreeStatsSeries;
New button at Series Stats dialog editor that allows removing (destroying) all series added using it
Added the Kurtosis:Double; function.
Added the Mean:Double; function.
Added the Skewness:Double; function.
Added the StdDeviation:Double; function.
30) TLegendPalette tool
New Title, SubTitle, Foot and SubFoot properties are now persisted at design-time and can be accessed also
by code:
TChart1.Tools.Items(0).asLegendPalette.Title.Caption = "Speed"
31) FastLine Series
New experimental code to draw multiple fast-line series in parallel using more than one CPU (see below for
complete info).
32) DragPoint tool
Implemented point dragging support for Polar (and Radar, WindRose) series.
Just add a DragPoint tool and set its Series property to a Polar or derived series.
New OnDragPointToolEndDrag event, called when the mouse button is released after a dragging operation.
33) TeeEditor
New option to disable manually editing at the “Data” tab of Chart Editor dialog (the TeeChartGrid control).
TeeEditor1.Options.EditData = False
Removed: Help button at chart editor.
The help file is currently obsolete and in *.hlp format, not generally supported in Windows Vista and later.
Available documentation and tutorials can be found at http://wiki.teechart.net
34) ICustom3DGridSeries
Speed improvement for all 3D grid series (ColorGrid, Surface, etc) by replacing a loop with a binary-search
algorithm in GetSurfacePaletteColor method which is used to calculate the appropiate color of a given “Y”
value using the Palette array.
Typical gains are about 30% faster for big series (for example a ColorGrid of 1000x1000 cells).
35) ILineSeries, IPolarSeries
New PointerBehind boolean property (default is False).
This applies to all series derived from Line and Polar that have a Pointer property. When PointerBehind is True,
pointers will be displayed behind the line (in 2D mode only).
Also the line draw style should be set to “dsAll” (to draw first all pointers and then a line using all points,
instead of one-point, one-line “dsSegments”)
TChart1.Series(0).asLine.DrawStyle = dsAll
TChart1.Series(0).asLine.PointerBehind = True
36) ILegend
New property DrawBehind (boolean, default False).
DrawBehind determines if the legend has to be painted below (behind) or on top of Chart.
This is useful when ResizeChart is False, to make the legend “float” over the chart.
TChart1.Legend.DrawBehind = True
Other changes
More colors added to AndroidPalette (Android Theme), from 9 to 14.
Chart Titles and Footers delayed creation (to increase speed when creating new charts)
TeeListBox control now correctly detects changes to TChart.Legend.CheckBoxes property to display a checkbox or
a radioitem for each series in the list.
ImagePoint series now reuses the new Pointer.Picture property instead of creating an additional internal one.
New icons for Series styles, with a more “modern” design.
Protection against exceptions when using the GDI+ canvas from inside a dll.
If the GDIPLUS.dll is not initialized by the caller executable, TeeChart GDI+ canvas now will detect this problem
and will use the old GDI canvas, instead of raising an exception.
See this blog page for more information.
This protection is also done at Chart Gallery panel control, used by many editor dialogs.
The new GDI+ Canvas IsAvailable boolean function returns False when GDI+ cannot be used in the current environment
(ie: inside a dll when the exe caller has not initialized GDI+).
Picture file size is now displayed at Image editor dialog.

ValueIndex'th point that is under the XY pixel parameters:
ASeriesIndex = TChart1.SeriesList.Clicked( x,y, ValueIndex )
Returns “-1" if no point of any series contains XY.
One example of use is at MarksTip tool, this tool calls
SeriesList Clicked method to obtain which series is under
the mouse cursor.
6) New Filled property (boolean, default False)
for ContourSeries.
This property is equivalent to setting Brush.Style
= bsSolid, but more convenient and easy to remember.
TChart1.Series(0).asCountour.Filled = True
7) Bar and HorizBar Series
Improved detection in mouse xy Clicked method for 3D Bar cubes
and diamond styles. The algorithm now includes the bar cube
sides in 3D view (orthogonal and perspective).
8) Series Marks
New marks style “smsLabelOrValue”. This is now the default Style.
If Series point label text is empty, uses point value instead.
TChart1.Series(0).Marks.Style = smsLabelOrValue
New Automatic property (of type TAutomaticMarks)
Note: This property is not yet handled by all series styles. So far
it is used by Map and World series.
The intention of “Automatic” is to perform several attempts to avoid
series marks overlap other marks or other parts of the chart. It is
True by default in all subproperties.
Note: The existing AutoPosition property is now deprecated and mapped
to the Automatic.Move property.
Marks will be first repositioned to avoid overlapping. Its after auto
positioning when Automatic.Hide takes place if the mark still can't be
appropiately displayed.
Automatic.Resize means the series will try to reduce the mark font size
to fit the mark inside the available space, before deciding to hide the
mark completely.
Automatic.Wrap means to split the mark text into several lines of text,
to try to fit the mark.
Automatic.Rotate means to rotate 45 or 90 degrees the mark, as it can be
sometimes more convenient to fit more marks.
9) Custom Series
New InflateMargins boolean property (default True).
When False, Line or Area series will not try to expand the axes to
accommodate for the border size. This is more noticeable when the
TChart1.Series(0).asLine.Pen.Width is bigger than 2.
10)Series Pointer
New Pointer Arrow style (psArrow enum type):
TChart1.Series(0).Pointer.Style = psArrow
New Picture property (of type TTeePicture) to display an image at
pointer.
TChart1.Series(0).Pointer.Picture.LoadFromFile("Fire.png")
New public properties:
SizeFloat (Single)
SizeUnits (suPixels or suAxis)
SizeFloat allows specifying pointer size with more precision (with decimals),
while SizeUnits lets calculate pointer size using axes scales instead of screen
pixels.
This means, when “suAxis”, zooming a chart will also display zoomed pointers.
This feature is primarily used internally by TMapSeries.
11)Gauges
Improved display of less-than-360 degree Circular gauge Frame border.
Smooth painting of range color lines (with more precision and antialias).
New Hands collection property for Circular Gauge. More than one “Hand” can now
be displayed. Each hand has its own formatting and Value.
The previous “Hand” property is still supported, but now refers to Hands[0] item.
New Circular gauge Hand style: psArrow (draws an arrow head at Hand end position).
TChart.Series(0).asCircularGauge.Hand.Style = psArrow
New Ranges[] collection property for Linear, Knob and Circular gauges, allows more
than two colored segments inside the gauges. Existing “GreenLine” and “RedLine”
properties are still supported, but they now refer to Range[0] and Range[1].
Each Range now supports displaying normal or “spiralled” segments. Each Range now
includes a new Position property (% radius from gauge center), and StartValue and
EndValue properties to define the Range boundaries.
New AxisRanges[] collection property, allows drawing Axes in range segments.
Each “range” segment has Format properties.
Automatic calculation of gauge axis Increment (the step between gauge axis labels),
to avoid overlapping labels. Same as with normal charts, automatic Increment when its
zero.
Circular Gauge axis labels are now displayed using the Axis DrawAxisLabel method
instead of a simple Canvas Texout. This allows supporting all Axis.Texts formatting
properties, like background, shadow, etc.
Gauge editor dialogs have been modified to support editing (and adding, deleting)
multiple Ranges and Hands items at design-time and runtime.
CircularGauge Marks now supported.
Gauge Hand value can be displayed using the default Marks property, located below the
gauge center.
TChart1.Series(0).asCircularGauge.Marks.Visible := True
12)Canvas
Improved support for semi-transparent (alpha) PNG images, for both GDI and GDI+ canvases.
Transparent PNG pictures are now correctly blended with the background
(note: TChart1.BufferedDisplay property must be True).
This applies to both Canvas Draw and StretchDraw methods.
New CubeHull method returns the polygon that encloses a 3D cube. It is used by CustomBar
series (to detect mouse clicks on 3D bars with the Clicked method), and Canvas ClipCube
method to limit drawing outside the 3D “cube” delimited by axes.
New internal IsAvailable boolean class virtual function.
GDI+ canvas overrides this function, see Other Changes below.
GDI+ canvas now correctly displays flat shadows when any object's Shadow.Smooth property
is False.
TChart1.Legend.Shadow.Smooth = False
OpenGL canvas improved display of Pen Transparency. And better Zoom matching when switching
from a non-opengl canvas.
13)WorldMap Series
World and Map series “Layers”.
“Layers” concept for Maps can be easily implemented by using additional series. Each Layer
being a different Series, with its own properties, and painted one after the other over the
same chart.
Also, more than one Map or World series can be used and combined in the same chart.
With this new release, Map Layers get more useful as there are new methods to handle GIS file
formats like Google's Earth KML with placemarks, and ShapeFile files containing polylines (roads, etc).
World Country names have been augmented with country ISO 2-letter codes (ie: Canada=CA) Series Marks
can now display country names, codes, or both.
China, France, Japan county maps are now included. One polygon is used for each county / province.
New TeeFlags.res resource, contains all country flags pictures as small gifs. These flags can be used
in World series to display them inside each country polygon, and also at chart grid when visualizating
country data.
To enable showing flags, a new property is introduced:
TChart1.Series(0).Flags.Visible = True
17) Map Series
New IMapPolygon Code (string) property. This is an alternative string to Text property, and can be used
when displaying Series Marks inside the polygon.
New TTeePolygon Centroid function (returns TPoint). Centroid returns the XY point inside the polygon that
is best equidistant to all polygon points. This is different than the middle XY position of the polygon
bounding rectangle.
Centroid position is used when displaying text Marks inside the polygon.
New IMapPolygon Picture property (of type IBackImage). Allows filling the polygon interior using an image.
New ITeePolygonGroup class, allows creating logical groups of polygons (shapes) to change properties of all
items with a single group property. Groups are used for example by World series to keep together continent
countries or country states or provinces.
New Shapes.ByCode array property, returns shape that has a given Code:
tmp = TChart1.Series(0).asWorld.Shapes.ByCode['CA'] ; // Returns shape that corresponds to “Canada”
New MapMarks property. Contains properties to customize displaying series text marks inside polygons:
TChart1.Series(0).asWorld.MapMarks.AutoSize = False
AutoSize (boolean default True), fits text inside polygon by changing font size.
Centroid (boolean default True), positions text at polygon centroid instead of center of polygon rectangle bounds.
TextStyle (mtLabel, mtCode, mtBoth) choose which polygon text to display.
Uppercase (boolean default False), when True, show mark text in uppercase.
New Pointer property (TSeriesPointer) and PointSize (Single).
These properties enable Map series to display items as simple “pointer” shapes instead of polygons. It is useful
for example to display thousands of dots over a World map, being each dot an Airport or a City or whatever.
When Point size is zero (the default), size is automatically changed when zooming the map.
TChart.Series(0).asWorld.Pointer.Style = psCircle
Several optimizations in Map series intended to improve the painting speed when zooming or scrolling maps. Best
speed is achieved when using an OpenGL canvas.
18) 3D / Palette Series
Added CountLegendItems function.
Added LoadPaletteFromFile method.
Added SavePaletteToFile method.
Color palette for 3D series can now display custom Text at Legend (runtime only):
The Legend TextStyle property is used like in all other series styles to determine when to use this palette text:
TChart1.Legend.TextStyle = ltsLeftValue
19) Tower 3D Series
New Stacked property.
Like in TeeChart for .Net, multiple Tower series can now be displayed as stacked (one on top of another).
TChart1.Series(0).Stacked = tsStacked
20) Chart Tools
MarksTip tool new property SystemHints (boolean default True).
When False, a normal ITeeShape object is used to paint the tiptool instead of using the VCL system
mechanism.
TChart1.Tools.Items(0).asMarksTip.SystemHints = False
TChart1.Tools.Items(0).asMarksTip.Format.Font.Size = 24
TChart1.Tools.Items(0).asMarksTip.Format.Font.Color = vbBlue
The only disadvantadge compared to system hints is the shape cannot be displayed outside the chart bounds.
When SystemHints is False, the new Format property (of type ITeeShape) contains all the formatting properties
(Brush, Pen, Font, etc) to display the hint.
21) TBackImage
New property DrawQuality : EStretchDrawQuality (default value: sqHigh):
TChart1.Panel.BackImage.DrawQuality = sqLow
22) TSeriesMarks
New property UseSeriesTransparency : Boolean (default True)
When False, series marks will be painted using their own transparency, without accumulating the marks series
transparency, if any.
TChart1.Series(0).Marks.UseSeriesTransparency = False
23) All Series
New ISeries.Legend property of type ITextShape.
This new property includes a Picture property to display an image or icon for each series at the Chart Legend
Symbol.
Thanks to this new property, the existing ISeries.ShowInLegend is now equivalent to ISeries.Legend.Visible,
and ISeries.LegendTitle is the same as ISeries.Legend.Text.
24) IImagePoint and IDeltaPoint
Improved painting of legend symbols, these series now show the corresponding image for each point at the legend.
25) ColorGrid, Surface, TriSurface Series
Speed improvements, caching calculated values to avoid repeating and spending time at each repaint (like when
doing zoom and scroll).
Adding or modifying series point values empties the cache so it will be recalculated at the next repaint.
26) Bar and HorizBar Series
Cylinders are now painted filling them with gradients, instead of drawing “sides”.
The output is of much better quality (and speed), although currently there is no rotation of gradients when the
chart is rotated with 3D perspective.
The ConePercent property (from 0 to 100, default 0) is now published (it was public).
27) Contour Series
Null values (in grid cell data) are now supported. Contour levels will not use null data.
TChart1.Series(0).SetNull( 23 ) ' ? point index 23 is now null
28) Polar Contour Series
New series style to display contour lines from XYZ data using Polar (Angle and Radius) coordinates.
This series is derived from Polar series class (to draw circular background, axes, etc), and includes a Contour
series internal field (to calculate the contouring lines, customize contour levels, etc).
“X” indexes are converted to angles (from 0 to 360 degree). For example if the 3D grid has NumXValues = 10, then every angle interval will be 36.
“Z” indexes determine the radius, and the “Y” values are used to calculate the level lines.
Data can be manually added using the Series1.AddXYZ or AddNullXZ methods.
Typical settings for geographical data are to set 90 degree at top (North), and drawing labels clockwise (270 = West, 90 = East).
TChart1.Series(0).asPolarContour.RotationAngle=90
TChart1.Series(0).asPolarContour.AngleLabels.ClockWise=True
29) SeriesStats Tool
New method to remove (destroy) all series that have been created using the Series Stats tool editor dialog:
TChart1.Tools.Items(0).asSeriesStats.FreeStatsSeries;
New button at Series Stats dialog editor that allows removing (destroying) all series added using it
Added the Kurtosis:Double; function.
Added the Mean:Double; function.
Added the Skewness:Double; function.
Added the StdDeviation:Double; function.
30) TLegendPalette tool
New Title, SubTitle, Foot and SubFoot properties are now persisted at design-time and can be accessed also
by code:
TChart1.Tools.Items(0).asLegendPalette.Title.Caption = "Speed"
31) FastLine Series
New experimental code to draw multiple fast-line series in parallel using more than one CPU (see below for
complete info).
32) DragPoint tool
Implemented point dragging support for Polar (and Radar, WindRose) series.
Just add a DragPoint tool and set its Series property to a Polar or derived series.
New OnDragPointToolEndDrag event, called when the mouse button is released after a dragging operation.
33) TeeEditor
New option to disable manually editing at the “Data” tab of Chart Editor dialog (the TeeChartGrid control).
TeeEditor1.Options.EditData = False
Removed: Help button at chart editor.
The help file is currently obsolete and in *.hlp format, not generally supported in Windows Vista and later.
Available documentation and tutorials can be found at http://wiki.teechart.net
34) ICustom3DGridSeries
Speed improvement for all 3D grid series (ColorGrid, Surface, etc) by replacing a loop with a binary-search
algorithm in GetSurfacePaletteColor method which is used to calculate the appropiate color of a given “Y”
value using the Palette array.
Typical gains are about 30% faster for big series (for example a ColorGrid of 1000x1000 cells).
35) ILineSeries, IPolarSeries
New PointerBehind boolean property (default is False).
This applies to all series derived from Line and Polar that have a Pointer property. When PointerBehind is True,
pointers will be displayed behind the line (in 2D mode only).
Also the line draw style should be set to “dsAll” (to draw first all pointers and then a line using all points,
instead of one-point, one-line “dsSegments”)
TChart1.Series(0).asLine.DrawStyle = dsAll
TChart1.Series(0).asLine.PointerBehind = True
36) ILegend
New property DrawBehind (boolean, default False).
DrawBehind determines if the legend has to be painted below (behind) or on top of Chart.
This is useful when ResizeChart is False, to make the legend “float” over the chart.
TChart1.Legend.DrawBehind = True
Other changes
More colors added to AndroidPalette (Android Theme), from 9 to 14.
Chart Titles and Footers delayed creation (to increase speed when creating new charts)
TeeListBox control now correctly detects changes to TChart.Legend.CheckBoxes property to display a checkbox or
a radioitem for each series in the list.
ImagePoint series now reuses the new Pointer.Picture property instead of creating an additional internal one.
New icons for Series styles, with a more “modern” design.
Protection against exceptions when using the GDI+ canvas from inside a dll.
If the GDIPLUS.dll is not initialized by the caller executable, TeeChart GDI+ canvas now will detect this problem
and will use the old GDI canvas, instead of raising an exception.
See this blog page for more information.
This protection is also done at Chart Gallery panel control, used by many editor dialogs.
The new GDI+ Canvas IsAvailable boolean function returns False when GDI+ cannot be used in the current environment
(ie: inside a dll when the exe caller has not initialized GDI+).
Picture file size is now displayed at Image editor dialog.

LinePointSeries.
13) [No bugfix log]
Exporting a large number of times the Chart to
PDF (i.e. 5000) in a loop "out of resources"
error appears. We've been investigating the
cause of the problem and trying to find a good
solution, however, we'ven't found a fix for it.
The problem is that when the Chart is exported
to PDF for a this large number of times, if
smooth shadows are used into the Chart, the
resources wasted are growing and growing until
the error appears. We've tried to control this
consumption with no luck.
So, at the end a workaround for these case when
the number of exportations are really big would
be to hide the shadows or just set the shadow
smooth to false.
14) [TF02012544]
Zooming or scrolling on a IBubbleSeries

13) [No bugfix log]
Exporting a large number of times the Chart to
PDF (i.e. 5000) in a loop "out of resources"
error appears. We've been investigating the
cause of the problem and trying to find a good
solution, however, we'ven't found a fix for it.
The problem is that when the Chart is exported
to PDF for a this large number of times, if
smooth shadows are used into the Chart, the
resources wasted are growing and growing until
the error appears. We've tried to control this
consumption with no luck.
So, at the end a workaround for these case when
the number of exportations are really big would
be to hide the shadows or just set the shadow
smooth to false.
14) [TF02012544]
Zooming or scrolling on a IBubbleSeries

- Related problem with "Out of system resources error using TeeChart in ASP page"
1. Resource issue when connecting to file based (mdb) datasources.
2. Resource issue when resizing TeeChart in a browser page during
cascade/un-cascade operations whilst having open several/many such pages.
Description
1. File based (mdb) datasources
High resource utilisation has proved to be an issue when connecting to file
based (mdb) datasources. Previous tests have shown that the same or greater
load when applied to an integrated dataserver (eg. MS's SQL Server) does
not suffer from similar resource l imitations. We recommend the use of that
type of database for applications where multiple access/high load to a
database is expected.
2. Resizing TeeChart during cascade/un-cascade operations
We can reproduce this issue. The problem occurs as a TeeChart internal bitmap
is being copied and requesting a windows handle during a TeeChart resize
operation in a child Internet Explorer window (here during the cascade/un-cascade
tests). In tests to date the problem seems to be limited to IE windows opened, as
child windows (ie. Ctrl-N from an existing Window).
In independently opened IE browsers and in Windows Form-based apps the problem
doesn't appear to occur. The problem occurs at a low Windows level that makes it
difficult for us to resolve the problem in TeeChart, not at least without further
investigating alternative techniques to achieve the required result. If the Chart isn't
resized the problem shouldn't occur and that has proved to be the case in tests here
to now - feedback on this would be useful. To avoid resize Charts can be fixed size
instead of percentage sized.
eg.
instead of
For regular TeeChart browser applications, where the need to load and resize multiple
child browser windows at a time is not necessary, the continued use of % sizing shouldn't
be a problem.
Conclusions
1. (mdb files) The issue is long-standing and related to resource use managed outside of
TeeChart. The recommended solution remains the use of a server-based database server.
2. (internal bitmaps) We are further investigating a fix to this issue that we feel is related to
an IE resource management deficiency. For the moment we recommend the workaround
described above.

1. File based (mdb) datasources
High resource utilisation has proved to be an issue when connecting to file
based (mdb) datasources. Previous tests have shown that the same or greater
load when applied to an integrated dataserver (eg. MS's SQL Server) does
not suffer from similar resource l imitations. We recommend the use of that
type of database for applications where multiple access/high load to a
database is expected.
2. Resizing TeeChart during cascade/un-cascade operations
We can reproduce this issue. The problem occurs as a TeeChart internal bitmap
is being copied and requesting a windows handle during a TeeChart resize
operation in a child Internet Explorer window (here during the cascade/un-cascade
tests). In tests to date the problem seems to be limited to IE windows opened, as
child windows (ie. Ctrl-N from an existing Window).
In independently opened IE browsers and in Windows Form-based apps the problem
doesn't appear to occur. The problem occurs at a low Windows level that makes it
difficult for us to resolve the problem in TeeChart, not at least without further
investigating alternative techniques to achieve the required result. If the Chart isn't
resized the problem shouldn't occur and that has proved to be the case in tests here
to now - feedback on this would be useful. To avoid resize Charts can be fixed size
instead of percentage sized.
eg.
instead of
For regular TeeChart browser applications, where the need to load and resize multiple
child browser windows at a time is not necessary, the continued use of % sizing shouldn't
be a problem.
Conclusions
1. (mdb files) The issue is long-standing and related to resource use managed outside of
TeeChart. The recommended solution remains the use of a server-based database server.
2. (internal bitmaps) We are further investigating a fix to this issue that we feel is related to
an IE resource management deficiency. For the moment we recommend the workaround
described above.
