Did ur image is shown on the screen using below line var image :Image; image.source=processUrlString+metricId+"&width="+imagewidth;
If yes then debug ur code and see the result and if no then check why the image is not being loaded.. I have shown u the way. Now debug the code and do some more googling to get the result.
