Steema Central

when I fill a chart like this:

for (int i = 0; i < 5; i++)
{
Steema.TeeChart.Styles.Series s = new
Steema.TeeChart.Styles.Points(tChart1.Chart);
for (int j = 0; j < 5; j++)
{
s.Add(j+i*10, j);
}

}

and then drag the chart contents to the left (right mouse button) an
IndexOutOfRange error occurs with the following message. It has something to do with the first points getting out of the visible range.

What am I doing wrong?

Hi FatDonkey,

I'm not able to reproduce this one using latest TeeChart for .NET v3 release available at the client area. Some similar issues have been fixed in last releases. Which version are you using? Can you please check if that solves the problem at your end?

Thanks in advance.

Hello,

I am using the latest release. I got the errors in a more complex project. To reproduce them I created an empty project/form, placed a Chart and controller on it and added the filling procedure (see first post).

I use VS2005 on win XP, SP3. I installed the latest updates for VS and .net.

I think it has something to do with the range of visible points. As soon as the left-bottom points are disappearing (when panning to the left) the exception is thrown.

Panning up, down or to the right works ok.

Zooming in on an area that would place the left-bottom point outside the visible range also throws an exception!

If it helps I can send you my project and executable.

This is the Exception text (this time on a clean Windows XP embedded, SP2). The exception occurs during FirstLastVisible index calculation.

System.IndexOutOfRangeException: Index was outside the bounds of the array.

Hi FatDonkey,

I'm not able to reproduce the problem here using code below. Could you please complete axes SetMinMax calls commented below so that we can reproduce the problem here?
Thanks in advance.

I placed your code in my project and filled in min and max values:

private void InitializeChart()
{
for (int i = 0; i < 5; i++)
{
Steema.TeeChart.Styles.Series s = new Steema.TeeChart.Styles.Points(tChart1.Chart);
for (int j = 0; j < 5; j++)
{
s.Add(j + i * 10, j);
}
}

tChart1.Axes.Left.SetMinMax(0,10);
tChart1.Axes.Bottom.SetMinMax(0,100);
}

The effect is the same. When panning to left an exception is thrown when the last point of the first series crosses the left axis.

Altering the code generates an immediate exception:

I've installed an old version: 3.5.3274.30663

Now it works!

Something is not right in your latest version.

Hi FatDonkey,

Thanks for your feedback. I could reproduce the issue here now using last maintenance release but checked it works fine using our current sources. So you can expect this being fixed for the next maintenance release which will be out before the end of the week.

Hello hchiker,

I have seen that your version of TeeChart.Net 3 is not the last. Could you please, update your version of TeeChart and try again if your problem persist?

Thanks,

Hi,
it seems that the version 3.5.3700.30575 correct this issue. I'll continue my tests and keeps you informed.

Thanks
