[yt-users] Custom Colorbar Axis

[Gabriel Goodwin]

Hello All,

Does anyone know how to specify the tickmark locations on the colorbar
axis? I am able to do this on the plot axes without issue, but have not
been able to successfully do the same with the colorbar.

Attached is a pic of one of my plots using default colorbar axis ticks. I
have tried to use the following code (and many variants of it I have found
in the python/matplotlib documentation) to specify the location of the
tickmarks, but they don't place the ticks accurately. My data is
temperature plotted over the range of 300K to 5500K and I want to have
tickmarks at 300K, 800K, 3500K, and 4500K. Also attached is pic of my plot
showing an attempted custom colorbar axis.

I'm not sure if it makes a difference, but I made the colormap in
matplotlib.

colorbar_axes = p.plots[string].cax
colorbar_axes.yaxis.set_ticks([0, 0.1, 0.8])

Thanks for the help!
