fill colorgrid with the color attribute

I noticed following problem when I filling the color grid series with color - attribute. I'm using the VS2002 and TeeChart 1.0.1644.16795.
When adding points to the colorgrid, it not set the value point colors correctly (it not scaling the colors) if right side of the colorgrid includes values with Color - parameter.
But if I do the same with TeeChart 1.0.1452.42972, then there is no problems.
Here's the example code, which not set the color correctly
Steema.TeeChart.Styles.ColorGrid colorGrid1 = new Steema.TeeChart.Styles.ColorGrid();
colorGrid1.Pen.Visible = false;
tChart1.Axes.Bottom.Automatic = false;
tChart1.Axes.Bottom.Minimum = 0;
tChart1.Axes.Bottom.Maximum = 200;
tChart1.Axes.Left.Automatic = false;
tChart1.Axes.Left.Minimum = 0;
tChart1.Axes.Left.Maximum = 100;
for (int i = 0; i < 200; i++)
{
for (int j = 0; j < 100; j++)
{
if(i < 10)
colorGrid1.Add(i,i * 0.5,j);
else if (i > 10 && i <50)
colorGrid1.Add(i,i * 0.5 ,j,Color.Transparent);
else if (i >= 50 && i < 90)
colorGrid1.Add(i,i * 0.5,j);
else
colorGrid1.Add(i,5,j,Color.Transparent);
}
}
colorGrid1.PaletteSteps=30;
colorGrid1.ClearPalette();
colorGrid1.UseColorRange = false;
colorGrid1.StartColor=Color.Green;
colorGrid1.MidColor=Color.LightGreen;
colorGrid1.EndColor=Color.White;
colorGrid1.UsePalette = true;
tChart1.Series.Add(colorGrid1);
BUT if you change the order of last two else statements, then it works:
else if (i >= 50 && i < 90)
colorGrid1.Add(i,5,j,Color.Transparent);
else
colorGrid1.Add(i,i * 0.5,j);

Hi HQO,
I've been able to reproduce it, and it's a bug.
I've already added it to our deffect list to be fixed for future releases.

ok, in our side we need that functionality end of this month so any plans when you release this new version?
And import thing, is that new version still VS2002 compatible?

Hi HQO,
Well, a workaround can be using 2 ColorGrid series because the problem is when switching from color to a palette. Working code would be:
Code: Select all
tChart1.Series.RemoveAllSeries();
Steema.TeeChart.Styles.ColorGrid colorGrid1 = new Steema.TeeChart.Styles.ColorGrid();
Steema.TeeChart.Styles.ColorGrid colorGrid2 = new Steema.TeeChart.Styles.ColorGrid();
tChart1.Aspect.View3D = false;
colorGrid1.Pen.Visible = false;
colorGrid2.Pen.Visible = false;
tChart1.Axes.Bottom.Automatic = false;
tChart1.Axes.Bottom.Minimum = 0;
tChart1.Axes.Bottom.Maximum = 200;
tChart1.Axes.Left.Automatic = false;
tChart1.Axes.Left.Minimum = 0;
tChart1.Axes.Left.Maximum = 100;
colorGrid1.PaletteSteps=30;
colorGrid1.ClearPalette();
colorGrid1.UseColorRange = false;
colorGrid1.StartColor=Color.Green;
colorGrid1.MidColor=Color.LightGreen;
colorGrid1.EndColor=Color.White;
colorGrid1.UsePalette = true;
colorGrid2.PaletteSteps=30;
colorGrid2.ClearPalette();
colorGrid2.UseColorRange = false;
colorGrid2.StartColor=Color.Green;
colorGrid2.MidColor=Color.LightGreen;
colorGrid2.EndColor=Color.White;
colorGrid2.UsePalette = true;
for (int i = 0; i < 200; i++)
{
for (int j = 0; j < 100; j++)
{
if(i < 10 && i < 90)
colorGrid1.Add(i,i * 0.5,j);
else if(i >= 90)
colorGrid2.Add(i,i * 0.5 ,j);
}
}
tChart1.Series.Add(colorGrid1);
tChart1.Series.Add(colorGrid2);
Another solution would be not using a palette.
ok, in our side we need that functionality end of this month so any plans when you release this new version?
TeeChart for .NET v2 is expected to be release before the end of this month.
And import thing, is that new version still VS2002 compatible?
Yes, TeeChart for .NET v2 will be compatible with VS.NET 2002.

I look the customer download site and there is only beta version available of TeeChart v.2
Also there was information that full version expires August 2005?
Is that the plan?

Hi HQO,

Yes, we have almost already finished. It is going to be released today. However it will only be available for those customers holding a TeeChart for .NET v2 license.
Also there was information that full version expires August 2005?
TeeChart for .NET v2 BETA version expires on August 2005
Is that the plan?
Registered version won't expire while evaluation versions are limited to 40/50 days.
Still problems

I updated the v2 (2.0.1938.29194) beta and still the same error occurs.
all colorpoints are solid when using the Color - attribute in add() method
if I use the old version of TeeChart (1.0.1452.42972) then colors of point are scaled correctly.
So, it seems that this new version not fix this problem? any workaround for this?
Here's the one example code what I have used:
Steema.TeeChart.Styles.ColorGrid colorGrid1 = new Steema.TeeChart.Styles.ColorGrid();
colorGrid1.Pen.Visible = false;
tChart1.Axes.Bottom.Automatic = false;
tChart1.Axes.Bottom.Minimum = 0;
tChart1.Axes.Bottom.Maximum = 200;
tChart1.Axes.Left.Automatic = false;
tChart1.Axes.Left.Minimum = 0;
tChart1.Axes.Left.Maximum = 100;
for (int i = 0; i < 200; i++)
{
for (int j = 0; j < 100; j++)
{
if(i < 60)
colorGrid1.Add(i,i * 0.5,j);
else
colorGrid1.Add(i,5,j,Color.Transparent);
}
}
colorGrid1.PaletteSteps=30;
colorGrid1.ClearPalette();
colorGrid1.UseColorRange = false;
colorGrid1.StartColor=Color.Green;
colorGrid1.MidColor=Color.LightGreen;
colorGrid1.EndColor=Color.White;
colorGrid1.UsePalette = true;
tChart1.Series.Add(colorGrid1);

Hi HQO,
No, I can see this bug (TF02010637) hasn't been fixed yet.
A workaround would be using 2 colorgrid series as I pointed you previously.
