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...
