Is there a way to specify the log/non-log scaling of a y-axis variable in create_profile or ProfilePlot.from_profiles? I have some profiles that start flat at an initial time and so the velocity_magnitude is everywhere 0. create_profile succeeds, but ProfilePlot.from_profiles generates a Matplotlib error before I have the ability to specify a scaling:<br>
<br>
sph = ds.sphere(ds.domain_center, ds.domain_width[0]/2)<br>
profile = yt.create_profile(sph, "radius",<br>
["density", "temperature", "velocity_magnitude", "dx"],<br>
extrema={'radius':(ds.domain_width[0]/ds.num_grid,ds.domain_width[0]/2.)},<br>
n_bins=int(ds.domain_width[0]*2.**(ds.max_level-1)),<br>
logs={'radius':False},<br>
units={'radius':'pc'})<br>
plot = yt.ProfilePlot.from_profiles(profile)<br>
<br>
