Is it possible to convert a chart to a bitmap file? It would be very helpful!

Thanks.

you can save the view as a bitmap:
if( false == view.isDrawingCacheEnabled()){
   view.setDrawingCacheEnabled(true);
}
Bitmap bitmap = content.getDrawingCache();

Can you provide an example of this ? , I can't see how I can access the bitmap 
without doing a custom mod of achartengine

Did you add the needed permission for that?
