This applet has taken me a LONG time to develop. The mathematics and
the graphics weren't bad, but the Java interface has driven me nuts
on more than one occasion. It still has, occasionally, some flaky
behavior that I can't seem to fix. So it goes.
- If the applet refuses to redraw the graph after you change
something, try clicking in a function text box and pressing
<Enter> or <Return> on your keyboard. Sometimes this
wakes it up, sometimes not.
- Sometimes the Zoom In/Out buttons don't display. I have no
idea. Clicking where the buttons are supposed to be generally
causes them to appear.
If you run across something that you believe to be a bug, I would
appreciate hearing about it. Please be as specific as possible - what
function(s) did you have, what window dimensions, etc.. I can't
guarantee that I can fix the problem in a timely manner, but I'll
If you have a suggestion for an improvement to the applet, I would
appreciate hearing about that, too.
All in all, I hope that the applet does the job for you.
