Although it occurs to me that you might be able to work around this behavior by doing something like:<div><br></div><div>slc = SlicePlot(ds, 'x', 'density')</div>slc.set_zlim('density', 1e-4, 1e-0)<div>
slc.set_log('density', True)</div><div><br></div><div>The key here is to call set_log after set_zlim.</div><div><br></div><div>Just for some context: it is set up that way to avoid a crash in matplotlib <span></span>which does not like creating logarithmic colorbars for data with zero dynamic range.</div>
