Hello VisAD comunnity,
I am facing a problem with the Display.IsoContour ScalarMap. In few
words, when I change the values, the Range dosen´t ajusts itself like it
does when I use another mapping like Display.RGB. It sounds like I am
missing something, but can be a bug also.
To make thing more clear, I am sending a single test that demonstrates
the problem.
Thanks already,
Cicero A. W. Zandoná
