Hello,
 
I am interested in learning how to increase the number of colors that show up on the tksurfer color bar.  Right now, I pretty much only get two or three colors at a time - blue, red, and yellow.  I see pictures in publications that show the whole rainbow:

Can anyone please explain the process to me of how to get this increased color range on the tksurfer maps?
 
Thank you very much,
Jeff Sadino
