TreeMap chart type in JFreeChart

Postby kontiky » Wed Oct 19, 2005 11:22 am

Hello!
For now exists new interesting chart type - TreeMap.
It is the most interesting for representing market data (look example here http://www.smartmoney.com/marketmap/?nav=hp_marketmap).
Whether there are plans to add TreeMap charts to JFreeChart?

It is not so hard, because here http://treemap.sourceforge.net/
exists free and open source library implementing TreeMaps. Unfortunately, this library not supporting for a long time.

You can read more about this chart type here

Thanks,
Andrew

Treemap in jfreechart

Well,

It would be very nice to integrate the capabilities of jTreeMap in jFreechart... One of the main features of a jTreeMap is the user interaction, the ability to drill down and zoom to some part of the map. It is powerful stuff.
