custom tooltip on TimeSeriesChart
Hi If anyone would have suggestions on how I can customize my tooltip text on my timeseries chart, it would be great. I am now showing the date (x-axis info) and the y-axis number.

CPU
Thanks a lot,
I tried the setnotify, and it seems to be working fine. I also had to make sure to call the series.clear() before updating the chart

eclipse problems
I actually had to extract all source files from Jcommon.jar as well as from jfreechart.jar and add it to my project before I packed it into a self-executable jar file. That is the only way to make the code portable. It is also ridiculous...I mean, what's the point of using a jar file for classes, if...
