Hi Molly,
I think this is a bug in yt - the issue is that the field_info associated
with the original profile object is not being saved to the profile dataset.
I've filed this issue here:
https://bitbucket.org/yt_analysis/yt/issues/1267
For now, you should be able to create a PhasePlot using the profile object
you created from the original dataset:
nhT_prof_new = yt.create_profile(sph, [('gas',
'H_number_density'),('gas','temperature')], fields='cell_mass',
extrema=extrema,fractional=True, n_bins=6)
plot = yt.PhasePlot.from_profile(nht_prof_new)
