My TeeChart version is Pro v6 ActiveX.
Could you provide sample codes about how can I add polygons in Map chart with c# language ?

Hi Quest,

I'm sorry but we don't have any C# example using TeeChart Pro ActiveX for that at the moment.

Anyway, at the forums threads below you'll find several examples. You shouldn't have any problem porting them to C#.

Hi Narcis,

Thanks for your reply.
I tried to wrote it as below, but it can not display any polygon besides Marks.
What's something wrong?

TeeChart.TChart chart = new TeeChart.TChartClass();
chart.AddSeries(TeeChart.ESeriesClass.scMap);
TeeChart.ISeries oSeries = chart.Series(0);
oSeries.Marks.Visible = true;
oSeries.asMap.Shapes.Add();
oSeries.asMap.Shapes.get_Polygon(0).Text = "Test";
oSeries.asMap.Shapes.get_Polygon(0).AddXY(0, 0);
oSeries.asMap.Shapes.get_Polygon(0).AddXY(0, 10);
oSeries.asMap.Shapes.get_Polygon(0).AddXY(10, 10);
oSeries.asMap.Shapes.get_Polygon(0).AddXY(10, 0);

Hi Quest,

It works fine for me here using TeeChart Pro v8.0.0.3 ActiveX. It may help you visualize the polygon adding following code:

Code: Select all

			chart.Axis.Left.MinimumOffset = 20;
			chart.Axis.Left.MaximumOffset = 20;
			chart.Axis.Bottom.MinimumOffset = 20;
			chart.Axis.Bottom.MaximumOffset = 20;

Or this:

Code: Select all

			chart.Axis.Left.SetMinMax(-5, 15);
			chart.Axis.Bottom.SetMinMax(-5, 15);

Hi Narcis,

I tried it, but can not visualize the polygon yet.
The Marks is always at 0,0 whatever the location of polygon.
Any setting I should append using v6.0.0.3 ?

Hi Narcis,

When I used the FillSampleValues method, the result is the same...
1. It can not display polygons beside Marks.
2. All Marks at the same location.

Hi Quest,

First of all, please notice there are newer TeeChart Pro v6 ActiveX releases available at the client download area. Could you please try using latest version available?

If problems persist, could you please send us a simple example project we can run "as-is" to reproduce the problem here?

You can either post your files at news://www.steema.net/steema.public.attachments newsgroup or at our upload page.

Thanks in advance.

Hi Narcís,

When I updated the newest version of TeeChart Pro v6, the web page displayed the exception "Can not generate ActiveX control xxx, because the current thread is not the single thread Apartment." at runtime.
Could you tell me how to solve the issue, please ?

Hi Narcís,
For the thread issue, I found the answer finally. It should set ASPCompat be true in .aspx.
Based on the example at Steema Software\TeeChart Pro v6 ActiveX Control\Examples\Visual Studio .NET\CSharpWebForm, could you tell me how to draw a LIVE chart (not a picture)? I tried it in many way, but not get a correct result.

Hi Quest,

You should do as in the example at C:\Program Files\Steema Software\TeeChart Pro v6 ActiveX Control\Examples\Visual Studio .NET\VBWebForm.

Hi Narcís,

Based on the VBWebForm example, I translated into C# as below:

Code: Select all

WebForm1.aspx.cs

TeeChart.TChartClass TChart1 = new TeeChart.TChartClass();
TChart1.AddSeries(TeeChart.ESeriesClass.scMap);
TChart1.Series(0).FillSampleValues(10);			
Response.BinaryWrite((byte[])TChart1.Export.asNative.SaveToStream(true));


WebForm2.aspx

<script language="VBScript">
  sub window_onload()
     Form1.TChart1.Import.LoadFromURL("http://localhost/TeeMap/WebForm1.aspx")			
  end sub
</script>

But I got a script error - "Out of memory" in WebForm2.aspx.

Hi Narcís,

Status update...
I dropped all codes beside <%@ Page ... %> in WebForm1.aspx, it will not show "Out of memory".

In the code that my latest posted, it can work normally if I use Export.asPNG. But it display nothing if I use Export.asNative.

Hi Narcís,

In the code that my latest posted, only the Map series will display nothing using Native exporting.

Hi Quest,

Yes, this is not supported in v6. This feature was implemented for TeeChart Pro v8 ActiveX.
