Question

Answer 1

charts4j is another good charting API. It uses the Google chart server to create charts and returns them to you as an image.

Answer 2

I think this librairy can help you: achartengine

Answer 3

I have successfully used AndroidPlot in the past to run line charts, but they also support bar charts. You can do it.
