Here is what I have. Still getting the same problem with chart not
initializing on my end. If you put in logs before and after the
constructor, it's returning somewhere in the chart constructor where it
calls its superclass constructor. I have no idea why though.

Ah right.  Don't worry about that. These methods will still work but
you're right, they might go away.  Instead, use
scheduleRepeatingImmediatelyAfter(new Steppable() { ... });  and
Frame.setVisible(true);

pack() does not set a frame to visible to my knowledge.

In the version of the code I sent you as well?  That would be most
unusual -- it works fine here.

Look carefully at the difference between your code and the one I
provided, particularly the init() and start() methods.  Since mine is
working, there's got to be some important difference.

Also, just for debugging consistency, make sure you're using the version
of JFreeChart that's provided in the libraries.zip file on the MASON
website.
