View legend symbols at custom location

[SK_1567]

Hello Team,

I am using Steema tee chart version for WPF 4.1.2017.2143.
As per my requirement, I need to show a legend symbols in a different table with project specific information. Is there any possibility to view legend symbols or repaint legend symbols at custom location.

Greetings,

Please see the following tutorial:

https://steema.com/docs/teechart/net/tu ... Design.htm

See this example for modification of the Legend symbols themselves at runtime:

https://github.com/Steema/TeeChart-NET- ... olFlags.cs

(whole project loadable here: https://github.com/Steema/TeeChart-NET- ... tDemoNET60)

Hello Marc,

Is there any update on this ?

Hello,

We were cross.checking options as it's not entirely clear to us from your description how you are creating the combined pdf output, and example of how you are doing that would be useful. On the other hand, we're still of the view that defining your own image symbol outside the Chart for your legend table (I assume that is outside of the chart) and then re-using that symbol in the Legend is the way to go.

The code for that is included in the example I linked:

for NET framework 4:

Code: Select all

private void Symbol_OnSymbolDraw(object sender, SymbolDrawEventArgs e) 
{
	if(this.checkBox1.Checked) 
	{
		Rectangle tmpR = e.Rect;
		tmpR.Inflate(-1,-1);

		System.Drawing.Bitmap bmp = new Bitmap(imageList1.Images[e.ValueIndex]);
		tChart1.Chart.Graphics3D.Draw(tmpR, bmp, Steema.TeeChart.Drawing.ImageMode.Stretch, false);
	}
}

In this case taking the image from a list, but you could assign your bitmap symbol here.

Hello Marc,

Thank you for your solution.

We want to do vice versa. We want to use legend symbol of a chart in a our PDF table so is there any way by which i can get series and its legend symbols.

Your help is very much appreciated.

Hello,

You can't get the symbol itself but you can get most of the information you need to plot it. The event from the previous examples offers up the rectangular size of the symbol to be plotted and the colours can be extracted from the Series value index, then knowing if you're going to have a square, triangular or line symbol according to default Chart settings, just use the PaintEventArgs e.Graphics in Form_paint or similar, to plot the symbol where you want it.
