I would suggest taking a look at Section 3 of Ugo's Tutorial:
http://www.ssec.wisc.edu/~billh/tutorial/s3/Section3.html
It starts out with an example of making and displaying a 2D field with a
regular domain topology with a single floating point value for each sample,
which is what I _think_ you're dealing with. He also has lots of excellent
information and examples for changing display attributes.
Hope that helps.
