Answer 1

Try this code

BarData chartData =...
BarChart chart = new BarChart(mContext);
chart.setData(chartData);

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();
