[gradsusr] Plotting or Masking missing data

[Adams, Jennifer M. (GSFC-610.2)[ADNET SYSTEMS INC]]

What you want to do is change the background color. Use the ‘set display<http://cola.gmu.edu/grads/gadoc/gradcomdsetdisplay.html>’ command. If you want a background color other than black or white, then use ‘set background<http://cola.gmu.edu/grads/gadoc/gradcomdsetbackground.html>’. Please read these doc pages carefully, because these commands behave differently depending on what version of GrADS you are using.

Jeff-

I was wondering how would you define color for missing data = NaN. The missing data plots as white but I want it black and have no idea.
