Steema Central

Hello,

I encountered a problem with importing .ten file and displaying map polygons with teechart 2 for C#. The step I did:
(1) draw map and add different colors to different polygons
(2) add customer axis labels to left and bottom axes.
(3) Save the chart to .ten file before closing the form
(4) Next time open the .ten file
All I can see is blanket polygons without color or wrong colors in some polygons. My customer axis labels are all gone.

So is there anything wrong with importing and exporting the .ten file for map polygons? The save method gave me the correct chart if the series is line series.

Thanks,

Hookem

Hello Hookem,

I couldn't reproduce your problem here.Please, could you send us a simple example project we can run "as-is" to reproduce the problem here?

Thanks,

Please try the following code:
//////////////////////////////////////////////////////
// button 1 used to draw map and save .ten file
private void button1_Click(object sender, EventArgs e)
{
tChart1.Series.RemoveAllSeries();
Steema.TeeChart.Styles.Map map1 = new Steema.TeeChart.Styles.Map();
tChart1.Series.Add(map1);
//map1.Brush.Color = System.Drawing.Color.Red;

Sandra,
The following two pictures are what is when i press button 1 (draw and save .ten file) and button2 (load .ten file)

The picture for load the .ten file.

Hello Andra,

Did you test the code I posted?

Thanks,

Hookem

Hello Hookem,

I have tested your project, and in version 4 of TeeChart.Net works fine. But we have found a problem with export and I have added it in bug report list with number [TF02014851]. We will try to fix it for next maintenance release of TeeChart .Net

Thanks,

When will the fixed release version be available? We will demo our software to our client next Friday and I don't want them to see that we can't open a project properly.

Thanks,

Hookem

Hi Hookem,

I'm sorry but I can't still provide an estimate date. TF02014851 issue has been logged into our bug tracking system today and has not been fixed yet. I recommend you to be aware at this forum or subscribe to our RSS news feed for new release announcements and what's fixed on them.
