Hi,<br><br> 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.<br>
<br> How can I do this?<br><br> Thanks,<br><font color="#888888">
