Hello.
Sometimes instead of chart appears the red cross - see the attachment. I can't reproduce it stable, so I'm not able to provide code example here. Could you tell me, which reason may be for such behavior?

Hi Ereona, Please provide more information - what is the platform, control verstion, are there any exceptions etc...

Dll's version is 12.5.9.12, OS is Windows 7. Unfortunately I can't tell anything about exceptions because this error reproduces only on user's PC so far.

Hi Ereona, We'll need some code or application that reproduces the problem or stack trace of the generated exception to further investigate this issue.

Here are stack traces for two exceptions which happen during chart repainting. How to avoid them?

Hi Ereona, As mentioned above you need to provide an app relicating the problem to investigate this in detail. Most likely you automate the control from a thread different than the UI main thread and that's why get those errors. If this is the case you need to ensure the chart document is protected from simultaneous access: nChartControl1.Document.Lock(); // chart modifications go herenChartControl1.Document.Unlock();
