Re: [jCharts-users] 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

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.
