Hello,

You can do something similar to the example Yeray posted here. That is also being explained in this article I wrote. Does this help you achieve what you expected?

I tried Chart1.draw, it works in the VCL but under Intraweb i have an exception:
'Le contrôle 'Control1' n'a pas de fenêtre parente'
I don't have this problem with TeeCreateBitmap, but I don't have the transparent background...

Hello,
The function Draw of the chart have problem only in GDI+.
So I have transparency now but only if I put this: Chart1.Canvas:=TTeeCanvas3D.Create.

I'm not sure about what TeeChart version are you using.
Note the "Control has no parent window" error in TeeChart for Intraweb and similars was fixed with the update for TeeChart Lite for RAD Studio XE5, as you can read here.
Are you using a TeeChart version published later to the 1st Feb 2014?

I use the last release 2014.11.140512, and I'm waiting for next release that correct some other problems.

Hello,

And have you tried with:

Code: Select all

aChart.BufferedDisplay:=False;
As suggested here?
