Legend with Continous = true and formatting of legind text

Hi,
1) How do I get the legend to span the entire ChartRect.Height? as shown in the attached graphs, it only spans the top of the chart?
2) How do I format the legend text so that it becomes - for instance - 128,6 instead of 128,577 ??

Hi Friis,
1. What about something like this?
Code: Select all
public Form1()
{
InitializeComponent();
InitializeChart();
}
private void InitializeChart()
{
tChart1.Series.Add(new ColorGrid()).FillSampleValues();
tChart1.GetLegendRect += tChart1_GetLegendRect;
tChart1.Legend.Symbol.Continous = true;
tChart1.Legend.Font.Size = 14;
}
void tChart1_GetLegendRect(object sender, GetLegendRectEventArgs e)
{
Rectangle chartRect = this.tChart1.Chart.ChartRect;
e.Rectangle = new Rectangle(e.Rectangle.Left, chartRect.Top, e.Rectangle.Width, chartRect.Height);
}
2. You can modify legend text format in the GetLegenText event, for example:
Code: Select all
void tChart1_GetLegendText(object sender, GetLegendTextEventArgs e)
{
double tmp = Convert.ToDouble(e.Text);
e.Text = tmp.ToString("0.000");
}

Hi,
1) This does not solve the problem - try to test the code I have made below on your system - can you reproduce the problem?
2) Thank you - I will use this
Code: Select all
public Form1()
{
InitializeComponent();
Make3DGraph();
}
public void Make3DGraph()

1) Perhaps I'm not explaining the problem well enough. The blue squared symbol with a value of 15.175 in the attached image "unknown.jpeg" - I would like to have that moved down to the very bottom and the red squared symbol with a value of 128.577 to stay at the top. In that way do make the legend values show a larger range of values and colors

Hi Friis,
1. This highly depends on the chart size. Another variable you can throw into the mix is
Legend.VertSpacing:
Code: Select all
this.tChart1.Legend.VertSpacing = 10;
You can make those values relative to the chart height.

Hi Narcis,
OK, vertspacing makes it look a little better...
But, for instance, in the attached image "unknown.jpeg" there are 10 symbols ranging from 0 to 128.577 - isn't it possible to increase this number to a larger number so that you accomplish a smoother gradient and larger gradient?
for instance, in the attached image "untitled.jpg" the legend is very smooth and there are an "unlimited" amounts of symbols ??

Hi Friis,
You'd better use LegendPalette tool for that. You'll find an example at "All Features\Welcome !\Tools\Legend Palette" in the features demo available at TeeChart's program group. This applied to your example:
Code: Select all
public Form1()

this.tChart1.BackColor = Color.White;
this.tChart1.Walls.Back.Gradient.Visible = false;
this.tChart1.Walls.Back.Color = Color.White;
this.tChart1.Walls.Bottom.Gradient.Visible = false;
this.tChart1.Walls.Bottom.Color = Color.White;
this.tChart1.Panel.Gradient.Visible = false;

Hi,
That looks MUCH better - Thank you
However, if I set the
Code: Select all
legendPalette1.Transparent = false;
this looks strange - the font at the legend palette looks bold ??

Hi Friis,
This looks like a bug to me. I have added it (
ID971) to the bug list to be fixed for future releases.

Hi Again,
How do I add a title to the legendPalette?
The following code does not work?
Code: Select all
legendPalette1.title.text = "sasasf";
and
Code: Select all
legendPalette1.chart.header.text = "dsf";
just adds a title to the chart itself ?

Yes; in the meantime, a simple workaround is this:
Code: Select all
private void InitializeChart()
{
tChart1.Series.Add(new ColorGrid()).FillSampleValues();
Steema.TeeChart.Tools.LegendPalette legendPalette1 = new LegendPalette(tChart1.Chart);
legendPalette1.Series = tChart1[0];
legendPalette1.Axes.Chart.Graphics3D.TextRenderingHint = System.Drawing.Text.TextRenderingHint.SystemDefault;
legendPalette1.Transparent = true;
}

Try:

legendPalette1.Axes.Chart.Header.Visible = true;
legendPalette1.Axes.Chart.Header.Text = "asasas";

Just implemented both of the solutions you have presented here - it works fantastic both of them - thank you
