You can use googlecharts for this.

Thank you,tufanv.

I want creat the chart on the device, rather than through network.

I understand the issue. I don't think that it is possible to antialias the clip boundaries.

You can probably remove the clipping and use DrawArc instead: http://www.b4x.com/android/forum/threads/half-of-a-circle.29302/#post-170109

Share(thanks for Erel's help):

1.Setting the antialias flag of the canvas.

2.Remove the clipping and use DrawArc instead for pie chart(need ABExtDrawings library).

Make Line charts and Pie charts show more smoothly( boundaries).

Charts moudle add two subs.
