got anybody experiences with canvases?
I want to put different graphs( till now drawn in the same canvas) upon the other, so that i could toggle between them without draw them again.
How can I do so???
Is there a possibility for transparent windows with canvases or can i make the canvas itself transparent???
Do you mean overlay the graphs so that one is visible under another, or do
you mean show one graph, then another? If you just want to switch between
graphs, you might use wxNotebook, with a wxCanvas on each tab.
If, on the other hand, you mean overlaying the graphs, then you could do
something like drawing to a bitmap (instead of directly to the canvas) and
then in your EVT_PAINT handler, only blit the bitmaps (with masks, to achieve
transparency) that you want to be drawn at the time (perhaps selected by a
set of wxCheckboxes).

If using a wxNotebook as Cliff suggested doesn't float your boat then
perhaps you just want to .Show(true) one panel and .Show(false) the others
as you toggle between them?
