Pls. see the attached images.
After I change from Teechart 7 to Teechart 2010.

Using Teechart 2010, The charts become very strange after pull down scroll bar.
But this program works fine by Teechart 7.
How do I solve this problem?

Hi Daniel,

You could try calling Draw() method at your ScrollBar OnChange event.

Also note that we've introduced some changes to the internal repainting for maybe related reasons, so this could fix you problem in the next maintenance release:

If you can send us a simple example project we can run as-is to reproduce the problem here, we'll try it in the latest sources so we can tell you if the next maintenance release will fix it or not.
Best Regards,
