is it possible to have a chart with transparent background, so that a
picture behind the plot is visible?
>From the wiki I understand that TAChart does not support BackImage property
as in Delphi, which would fit the purpouse.
However I read thay using BGRAbitmap as a back-end it is possible to use
transparency. I managed to install the required packages and activate the
back-end, but I did not understand from the tutorial (
http://wiki.freepascal.org/BGRABitmap_tutorial_TAChart) how to go on.
Does anyone has an example?
Thanks a lot,
