回答1:

To "paint" a graph on android you can use a third-party-lib. All libs supports different types of charts.

There are some graph-libs for Android:

1. afreechart is based on jfreechart. License: LGPL Version: 0.0.4

2. AChartEngine
   License: Apache Version: 1.2.0 Maven: yes. (custom repo?)

3. AndroidPlot License: Apache Version: 0.6.0 Maven: yes

4. GraphView
   License: Apache? Version: ? Maven: ?

I've found not so much about it. But it seems to be free.

1. DroidCharts License: LGPL Version: r2? Maven: ?

2. Chartdroid
   License: Apache Version: 2.0.0 Maven: ?

Or you implements your own :) It's not the perferct answer, but maybe a good hint.

you can use achartengine to create different kinds of charts. For example you can find lots of links like these two

link1, link2
