Plot and annotate random points

I have tried hard but cannot find a way to plot a number of random points and put a text annotation on each of the point.

My plot is very simple. Here are the points {(1,5),(1,10),(2,3), (7,10),(9,11),(9,13)} For each of the point plotted, I would like to add a text annotation on top of it.

I have searched high and low looking at scattered chart, bar chart, series chart, etc but cannot find a way to do what I wanted to do.

Solution

  • I was with the same problem, as far as I know achartengine doesn't support annotations currently (I asked on forums).

    Android Plot and other free chart solutions mentioned here doesn't support annotations, the only one is AFreeChart which is a port of JFreeChart for Android, I am currently using it and it is awesome and has much more features than achartengine.

    EDIT:

    See here, I have modified ace source code to have annotations capabilities.
