Contour Scaling Issue

[MartinB]

Hello,

I use the WPF version of TeeChart (4.1.2012.09280 ) and I would like to plot a contour type chart.

I use a regulard grid to fill the chart, and it seems when the property FillLevels is set to true, there is a vertical axis problem.

In fact the value supposed to control the color is virtually added on the chart with the wrong position ( The x position is fine, but the y position gets the z value ) which leads to a scaling problem, everything is compressed to the bottom.

I think there is a bug here, and in order to reproduce it you can simply create a chart with defaults settings, add a contour serie, activate the FillLevels and add something like :

for (int i = 1; i <= 10; i++)
{
for (int y = 1; y <= 10; y++)
{
m_Contour.Add(i, i*y, y);
}
}

Instead of getting the maximum left axis value equals to 10, it is 100.

Maybe this is fixed in the new version from february ?

Thank you

Hello MartinB,

I have made a simple code:

Code: Select all

 private void InitializeChart()
        {
            tChart1.Aspect.View3D = false;
            Steema.TeeChart.WPF.Styles.Contour m_Contour = new Steema.TeeChart.WPF.Styles.Contour(tChart1.Chart);
            tChart1.Aspect.View3D = false;
            m_Contour.FillLevels = true; 
            for (int x = 1; x <= 10; x++)
            {
                for (int z = 1; z <= 10; z++)
                {
                    int y = x * z;
                    m_Contour.Add(x, y, z);
                }           
            }
}

And using this I have gotten next image:

Therefore, using latest version seems your problem with axis left doesn't appear. Could you please check my code and confirm us it works fine for you when you use latest version of TeeChartFor.Net?

Thanks,

Hello Sandra, thank your for your answer.

Unfortunately, I updated my version to 4.1.2012.1312 and I still have the same problem.

I used your code, and this time I soon as I resize my window or I unzoom, the chart becomes this:

Hello MartinB,

Can you please attached for us a simple project because we can find your problem here and try to suggests a solution for you?

Thanks,

[MartinB]

Sure, I attached the project.

You can see that at first, it is correctly displayed, and as soon as I resize the window several "contour1" appear in the legend and I have the scaling problem.

Thank you

Sorry the file was too big, here it is

Hello MartinB,

Seems there is a bug in WPF version. I have added it in bug list report with number [TW16016607]. We will try to fix it to upcoming versions of TeeChartFor.Net.
