Below is a piece of code that gives you the functionality you expect.



var sourceBitmap:BitmapData = new BitmapData(myChart.width, myChart.height,true,0x000000);
sourceBitmap.draw(myChart);  
//prev image is the "Image" variable name
prevImage.source = new Bitmap(sourceBitmap);

  • use infranview to change the background of the image from white to transparent (by saving as PNG).
  • use flex as usual
  • profit!
