Polar Brush always paints to 0,0

[GordonLindsay]

Hi,
I am using the polar series (from version 1.1.2004.16592) and I am struggling to get the polar.Brush to paint where I want it to paint.

I have a few points which I want to fill in with a colour, i.e:
Direction,Value
140,20
160,20
180,20
160,30

Now, you would think that by setting the CloseCircle, Brush.Color and Transparency that it would only fill in the area defined by these points. It does BUT it also fills in an area up to 0,0.
The Pen correctly join the points.



Im pulling my hair out trying to get it to work and may even implement my own custom painting as a work around...

Any help out there?

Hi GordonLindsay,

I'm not able to reproduce the problem here using build 1.1.2531.28391, which is the latest TeeChart for .NET v1 release available at the client area. Could you please try if this version solves the problem at your end? If not, could you plase send us a simple example project or code snippet we can run "as-is" to reproduce the problem here?

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

Thanks in advance.

Hi, Thanks for your prompt reply.

I have downloaded version 1.1.2531.28391 and the problem still remains. Here is the picture of what happens. It fills up to 0,0 even though I have no point at 0,0!



This image is taken from a simple example I have created to demonstrate the problem.

To reproduce: In VS2005, create a WindowsApplication with a TChart object on it and add the following code to the Load event.

Code: Select all

private void Form1_Load(object sender, EventArgs e)
{
    tChart1.Dock = DockStyle.Fill;

    // set chart properties
    tChart1.Aspect.View3D = false;
    tChart1.Chart.Axes.Left.Automatic = false;
    tChart1.Chart.Axes.Left.Minimum = 0;
    tChart1.Chart.Axes.Left.Maximum = 40;

    // create series
    Steema.TeeChart.Styles.Polar polar = new Steema.TeeChart.Styles.Polar(tChart1.Chart);
    tChart1.Chart.Series.Add(polar);

    // set polar properties
    polar.Color = Color.Black;
    polar.Circled = true;
    polar.CloseCircle = true;
    polar.CircleLabels = true;
    polar.ClockWiseLabels = true;
    polar.RotationAngle = 90; // north being 0 degrees
    polar.RadiusIncrement = 10;
    polar.AngleIncrement = 22.5;

    // set Brush
    polar.Brush.Color = Color.Aqua;
    polar.Brush.Visible = true;
    polar.Brush.Transparency = 0;

    // add points and angles: 140,160,180,160
    polar.Add(360 - 140, 20);
    polar.Add(360 - 160, 20);
    polar.Add(360 - 180, 20);
    polar.Add(360 - 160, 30);
}

Thanks for your help,
regards
Gordon.

Hi Gordon,

Thanks for the information. I've been able to reproduce the issue here and added it (TF02012935) to our defect list to be fixed for future releases.
