OK, I'm trying to put two JPlotLayouts in a JFrame, using a GridLayout. 
I wrote a test program that puts a JPlotLayout in the frame by itself
with some dummy data.  It works fine.  I then added a second plot, and
it appears, sort of.  The second plot's axes aren't there, and the
titles don't appear either.  There are three sets of data in the first
plot, and three in the second, but the only data that appears in the
second plot is the third data set from the first plot (got all that? :-)
).

I've attached the source code I'm using.  It's short, so I hope this
doesn't spam the list too much.

My questions are:
1) Why don't the titles for the second plot appear?
2) Why doesn't the child label appear in the second plot?  (The one with
the "CHILD LABEL" text)
3) Why don't the axes appear in the second plot?
4) Why does one data set appear in the second plot, but not the others?

Thanks for your help!
