I want to convert a line graph I made with AChartEngine lib to bitmap.How should I do?I didn't found on the net anything that can help. Is the toBitmap() method suitable?if yes then how to use it?

Update: I used this method :

 public static Bitmap loadBitmapFromView(View v) {  
v.setDrawingCacheEnabled(true);
v.layout( 0,0,800,600);
v.setDrawingCacheQuality(View.DRAWING_CACHE_QUALITY_HIGH);
v.buildDrawingCache();
v.getDrawingCache();
 Bitmap bmp = Bitmap.createBitmap(800,600, Bitmap.Config.ARGB_8888);
v.setDrawingCacheEnabled(false);
return bmp; }

and saved the result in a png file but all I got is an empty file !
