ClipRectangle function not working in an ASP.NET page

[Heraclitus]

I am using TeeChart.NET version (2.0.1992.14012), and I am running into a problem with clipping series values that are greater then the max set for a custom axis.

In my case, I have three different vertical custom axes on a particular chart. Each custom axis has its max and min set programmatically (instead of automatic). The problem is that some of the series data is greater than a particular custom axis. Hence, the line drawn goes right past a custom axis and into another.

I used some code from the TeeChart samples project under All Features -> Axis -> Opaque zones to try and clip the larger series values. This did not work.

Here is a relevant code snippet:

Code: Select all

private void series1_BeforeDrawValues(object sender, Steema.TeeChart.Drawing.Graphics3D g)
{
    Steema.TeeChart.Styles.Series series = sender as Steema.TeeChart.Styles.Series;

    if (series != null)
   {
        int left = series.GetHorizAxis.IStartPos;
        int right = series.GetHorizAxis.IEndPos;
        int top = series.GetVertAxis.IStartPos;
        int bottom = series.GetVertAxis.IEndPos;

        g.ClipRectangle(left, top, right, bottom);
    }
}

private void series1_AfterDrawValues(object sender, Steema.TeeChart.Drawing.Graphics3D g)
{
    g.UnClip();
}

Hi Heraclitus,

Instead of using UnClip method you'd better use ClearClipRegions.

Hi Narcis,

Thank you for the quick reply.

Unfortunately, I was not able to find a function called ClearClipRegions in my version of TeeChart.NET. I also could not find this function in the installed help. Can you direct me to where this function is?

Thanks again.

Hi Heraclitus,

Try using:

Code: Select all

		private void series1_AfterDrawValues(object sender, Steema.TeeChart.Drawing.Graphics3D g) 
		{ 
			g.ClearClipRegions();
		}
