Replace Chart with a bitmap
Posted: Mon Apr 05, 2010 12:33 pm
I have a bitmap of a color grid that I generate manually that I would like to place on a TChart. The manually built bitmap matches the ColorGrid series, but I can generate and display it much faster than TChart can. I tried pasting this bitmap onto the chart using "BackgroundImage" which does work, but it is just that... a background image. The empty chart is on top of it. I tried various combinations, but have not hit upon the correct code to make this work. Any help would be appreciated.
Currently, I just display my bitmap on a separate form. Displaying this form while inhibiting the TChart effectively doubles my refresh rate for a 50 x 1024 grid.
thanks,
Kev
