Re: How to render Axis Charts

I know you have to repaint the screen every time you resize your 
screen.  But my problem with JDK 1.4.1 on Mac OS X 10.2 is nothing 
gets displayed when you run the program first time from the command 
line.  It just sits there and does nothing.  But if you run the same 
program against 1.4.2 (that is only available for OS X 10.3), all the 
components are displayed properly (as far as I can tell).  But you 
see an error message in the chart that says "problems" in italics 
bold at the bottom of the screen.  So something is not being 
interpreted properly.  It works beautifully on Linux.  I'll try this 
on Windows, Solaris, and DEC Alpha and report the outcome in about 2 
weeks.
