Before this demo works, you need to download JFreeChart and make matlab get to know with it. There are 2
ways you can do this:
1. Add the jcommon and jfreechart jar to the dynamic matlab JavaClassPath (uncommented lines in the first
cell an change path to your local installation path)
2. Add the jcommon and jfreechart jar to the static matlab JavaClassPath (see Matlab Help, modify
classpath.txt on matlabroot\toolbox\local)
