IndexOutOfRangeException raised activating point series

[Luigi S.]

Hi again,
my application contains a TeeChart with three Point series (and some other FastLine, Line and Shape series): two of them are usually active and one is non-active. When I activate the third one, i get an IndexOutOfRangeException whose call stack is the following :

Code: Select all

   in Steema.TeeChart.Styles.ValueList.get_Item(Int32 index)
   in Steema.TeeChart.Styles.CustomPoint.CalcFirstLastVisibleIndex()
   in Steema.TeeChart.Styles.Series.DrawSeries()
   in Steema.TeeChart.Chart.InternalDraw(Graphics g, Boolean noTools)
   in Steema.TeeChart.Chart.InternalDraw(Graphics g)
   in Steema.TeeChart.TChart.Draw(Graphics g)
   in Steema.TeeChart.TChart.OnPaint(PaintEventArgs pe)
   in System.Windows.Forms.Control.PaintWithErrorHandling(PaintEventArgs e, Int16 layer, Boolean disposeEventArgs)
   in System.Windows.Forms.Control.WmPaint(Message& m)
   in System.Windows.Forms.Control.WndProc(Message& m)
   in System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m)
   in System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)
   in System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

I know that the problem explained is a little too "vague" and unfortunately in this case It's not easy for me to provide an example project that reproduces the problem ...
I could try to export series data in an XML file or something similar, but what about chart settings (axis limits, etc...) ?

Thanks.

A couple of notes:
- The horizontal (X) axis of the chart has DateTime property=true and the min and max property of this axis are set manually (Automatic=false)
- I noticed that the exception is thrown when i "move" the current "sliding window" (changing the min and max limits of the chart): it seems that the problem occurs when only particular points need to be shown...

Hope this can help....

One more note:

The problem seems to occur only in version 3.5.3330.21113 of TeeChart... I rolled back to an older version (3.5.3274.30663) and it seems to work fine.

Hi Luigi,

To be able to help you is very important that we can reproduce the issue here. It would be very helpful if you could arrange a simple example project we can run "as-is" to reproduce the issue here. Alternatively you could try exporting your chart to a native template file (*.ten) and let us know the exact steps we should follow to reproduce the issue here.

For more information on how to export charts please read Tutorial 12 - Exporting and Importing Charts. Tutorials can be found at TeeChart's program group.

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

Thanks in advance.
