thanks for the tips!  Just to be absolutely clear, what are the reserved
characters that can't be used in VisAD "names"?  In one instance I see "
", "(", ")" and "."  Looking at Bill's initial email response showing
the example

 (time -> ((x, y, z) -> (t, p)))

one might infer that "-" and ">" are also reserved?

thanks...  dlf

Thanks, Curtis, for jogging my memory. There is a method
ScalarMap.setUnderscoreToBlank() that will do this on axis labels.

Thanks, Bill

This wouldn't work: it would break the code that parses more
general MathType expressions like:

  (time -> ((x, y, z) -> (t, p)))

I recommend using underscore "_" in place of spaces in RealType
names. I really dislike the use of spaces in Windows file names,
because of all the trouble they cause with programs that need
file names as arguments.

I believe VisAD includes methods that let you alias RealType
names to other strings that do include special characters.
Perhaps someone who uses these methods can fill you in.
