colorbar

[doutriaux1]

Hi Folks:

Please address the following colorbar issue in vcdat2.0: The colorbar has the range -0.5 to 0.5 (with arrows for more extreme values) and should be symmetrical about 0.0, using an increment of 0.1, but there at two incorrect labels indicating -0.0 and 0.0.
I also suggest that as part of gui there should be a button to select a new color table. I have many color table in my initial.attributes, but presently I can only access them via the command line.
Template, Graphics Method, and Color Table editing would be helpful.
