Zoom and Pan

Post by kmanuele » Thu Oct 02, 2014 8:41 pm

XE3 Builder, VCL 2014

This has not been a good upgrade from VCL 2012. New problems:

Panning (via right mouse button) draws outside of the panel margins --- no clipping is happening.

Zoom has similar problem. Draws the zoomed area way outside the axes limits, though the axes limits scale correctly.

I get random access violations in msvcrt.dll during zoom, pan, or form resize ---- not sure which.

Note that I have GDI+ enabled.

It doesn't happen to me here.
Can you please arrange a simple example project we can run as-is to reproduce the problem here?
Worth to mention here Chart1.ClipPoints is true by default, but you could forcing it to see if it changes anything:

Code: Select all

Chart1.ClipPoints:=true;

Did you have GDI+ enabled when using TeeChart v2012?
And what build, 2012.05, 2012.06 or 2012.07?

I wasn't aware of the ClipPoints option, and I must have set it false unintentionally in the designer.

Thanks for the suggestion.

Will try to reproduce msvcrt.dll access violations.

I did not have GDI+ enabled in VCL 2012
VCL 2012 was Build 2012.07.121105

Thanks

Kevin
