It's a very general error: it means the applet failed to load.  You
have to look into Firefox's console to see what the actual error is.
My guess is that your mason.jar file does not include the jfree
classes (which are necessary to run the charting).  The make command
we have in MASON does not include those classes.  The easiest way to
deal with this is to UN-jar ( jar -xvf ) the jfreechart, jcommon, and
itext jar files.  These will produce the directories 'org' and 'com'
directories.  Put these directories inside the mason directory.  Then
call 'make jar'.  Understand that this will produce a large file with
a great many unnecessary classes, but my guess is it'll work.

Not at present.  The only way I can think about doing it, short of
whipping up the code in MASON, is to use the program Snapz Pro on the

I should mention that we're about to release a FAR improved charting
facility for MASON.  I think you'll be impressed.
