Multiple TimeSeriesDemo alá JFreeGraph-Demo

The code behind is just a demo of what is possible with JFreeChart using it in Matlab. I played a little
with codesnippets I found on the web and the API-Documentation.
(http://www.jfree.org/jfreechart/api/javadoc/index.html). When you want to explore the whole functionality,
I think it is better to buy the JFreeChart Developer Guide (http://www.jfree.org/jfreechart/devguide.html).

This function shows the different between 2 random series as an example of JFreeChart
(http://www.jfree.org/). The Idea to this code is based on the UndocumentedMatlab-Blog of Yair Altman, who
shows a sample Code of JFreeChart for creating a PieChart
(http://undocumentedmatlab.com/blog/jfreechart-graphs-and-gauges/#comments)

Within the plot you can zoom by pressing the left mouse button and moving the pointer. Also you have some
properties by right-clicking on the chart.

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)

Finally you must donwload jcontrol from Malcom Lidierth
(http://www.mathworks.com/matlabcentral/fileexchange/15580-using-java-swing-components-in-matlab).

Hi Thierry,
you're right. I tested it with version JFC 1.0.13.

Hi Sven
In the Requirements you point at two versions of JFreeChart. Only one (the latest) is sufficient, isn't it?
