You need to measure it by yourself:

chart.measure (View.MeasureSpec.makeMeasureSpec (300, View.MeasureSpec.EXACTLY), View.MeasureSpec.makeMeasureSpec (500, View.MeasureSpec.EXACTLY));
chart.layout (0, 0, chart.getMeasuredWidth (), chart.getMeasuredHeight ());

Bitmap chartBitmap = chart.getChartBitmap ();
