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. tom -- Tom Whittaker (tomw@xxxxxxxxxxxxx) University of Wisconsin-Madison Space Science and Engineering Center Phone/VoiceMail: 608/262-2759 Fax: 608/262-5974
