Hello,

I am using TeeChart v7.0.0.5 on Windows XP. This problem occurs both in Visual C++ 6 and in Visual Basic 6.

I got an Access violation exception that is very easy to reproduce. I am not sending an example project since there's absolutely no code to write. Simply pop in a TeeChart on a form, add a ColorGrid series, and set IrregularGrid to true. Do not populate the series.

Run the application and move mouse over the chart. This produces an Access Violation exception. It is a first-chance exception, it is handled using a messagebox.

As soon as there's data in the series, moving the mouse does not crash the application.

Thank you,
Alex

Ok, now I've stumbled on a problem that requires me to send code

I have a chart with one ColorGrid series. I add values dynamically, one row at a time. That project also demonstrates the previous problem of access violation, if mouse hovers over the chart on startup, when the ColorGrid is empty. But the problem I have is somewhat different now.

Settings are initialized in OnInitDialog(). That's where you can set IrregularGrid on and off to see what I mean. Values are added in EmulateSample().

When IrregularGrid is True, the grid colors are not smooth anymore. When IrregularGrid is False, and distance between X values is a fraction, the entire series is "rocking" left and right as values are added.

This "rocking" is not due to palette change that happens as higher values get added.

Am I missing something? Is there a way to fix this on my side?

Thank you,
Alex

Hello,

Have you been able to reproduce problems that I have reported in this thread? Should I create other example projects that demonstrate the problems?

Thanks,
Alex

Hi Alex,

Sorry for not having replied earlier. This has already been fixed and will be included with v7.06 maintenance release.
