Chart scrolling very slow after upgrade to TeeChart 2013

Post by dummzeuch » Thu Jan 23, 2014 4:11 pm

I just upgraded an existing (Delphi 2007) application to TeeChart 2013 and noticed two problems:
1. There seems to be a redrawing issue if TGdiPlusCanvas is used (I'll post about that in a different message)
2. After switching to TTeeCanvas3D using this code:

Code: Select all

TheChart.Canvas := TTeeCanvas3D.Create;
The scrolling is very slow.

What is the recommended way to getting the previous drawing method and speed (TeeChart 4.08) back?

I don't really want any new features for this program, just the old functionality with the new component.

Hello,

We'd better continue the discussion about this in the other thread you've opened:

Difficult to say without more information.
Could you please arrange a simple example project we can run as-is to reproduce the problem here?
Thanks in advance.
