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.

Screen shot of my latest j2me work to write a chart plotting API, you can see it in the Nokia series 60 emulator and the Default Color phone emulator from j2mewtk. Although it can contain a lots of bells and whistles, I plan to keep it simple to be viewable on all screen sizes, however, applications need to check for color, gray scale or monochrome device.

A lot more to come in this category, I am in the process of converting my website (Sep 2007) so come back soon.
