Hi Olver,
Thanks for the more detailed information. I tracked down your
problem to a bug in VisAD. An updated version of VisAD containing
the fix will be available on our FTP server within a few days.
Until then, I've made the fix available from:
http://palm.ssec.wisc.edu/Real.java
http://palm.ssec.wisc.edu/ScaledUnit.java
Just download the above two source files, place them in your main
VisAD directory (overwriting the old versions), then recompile them.
Cheers,
Curtis
