Hi Chang-Goo

If you explicitly set the limits of the colorbar using the set_zlim function you will avoid the zero dynamic range check.  That will also keep the colorbar limits the same from frame to frame.

Hi all,

When initial condition is uniform, it has zero dynamic range. Although it has no dynamic range, sometimes I need to plot it with log scale colorbar to make a movie with the same colorbar for later times. But, yt forced switch to linear colorbar. How can I make yt not to do that.

Thanks,
