Overview:
Currently un-named, its goal is to provide a chart drawing package based on MIDP 1.0 specifications. Another goal is to make this package open-source, see help required below.
Status:
- Line charts are complete
- Pie charts are complete
- Bar and Bar with Line charts are working but require some minor changes
- Data can be given in categories and multiple lines and bars are drawn
- An area of the screen can be given for charting while application uses the rest of the screen
- With a sample application the obfuscated jar is 16 KBytes and takes 52 KBytes heap memory on the Nokia Series 60 emulator
- Axes drawing is partially working (lables and markers are missing)
TODOs:
- Customizations in drawing charts (Point circles, Axes stepping, lines in BarCharts, etc.).
- Chart titles, Axes titles, Data titles, Legend Charts for better explanation of charts.
- Finding a way to release the API in a way that source is hidden (till opensource efforts succeed).
Screen Shots:
Here you see a simple midlet on a Nokia 3650, with the charts occupying the whole j2me canvas area.

Hi, it’s possible to have a look at the source code? I have to write a j2me application that graphs some temperature read in a sensor network and I’m stuck in having the line graph plot in the right way.
Thanks, Giacomo

This library is not in opensource yet, neither there is a way where I could give you an obfuscated binary library to be used in J2ME projects, so for now I can only sell the code, if you are willing.

Hello tazzix,
I am ending my final project in the university and I really need your help, because I need put in my application a bar chart.
The code can be obfuscated binary library.
Would you say me if this library works with framework LWUIT(https://lwuit.dev.java.net/)?
Could you help me?
Thanks a lot,
