[yt-users] Non-log scale for colorbars

[Nathan Roth]

Hi,

  I'd like to be able to set up my color bar so that it chooses the velocity
gradient based on a linear, and not a log, scale. One of the reasons I would
like to do this is to address the fact that yt plots white space on my slice
whenever the field I am plotting is exactly zero. Also, this will help me
compare my results to those performed by another code.

  How can I do this?

  Thanks,
  Nathan
