Hi Nathan,
Thank you!
 I am trying to make phase plot but wanted to change the axis labels and fonts etc. It is very simple script and should have worked as I followed the discussion on this thread.  My y-axis label command is simply being ignored. Any thoughts on this?
 plot = PhasePlot(dd, "Density", "Temperature", "CellMassMsun",
                 weight_field=None, fractional=True)
ax = plot.plots['CellMassMsun'].axes
ax.set_ylabel(r'$\mathrm{Density [g/cm^{3}]}$')
plot.reset_plot()
plot.save()
Cheers
Latif

Hi Latif,

Can you give a little more detail about the problem you're having.  Specifically, can you write a short script that isn't working for you?  If you see any traceback errors can you also paste the full traceback?

Hi all,
I am still having the same problem which Stephanie pointed out. Label setting is not working with the following version of YT. Any ideas what is going wrong here?

Version = 2.7-dev
Changeset = c03ad444c015
Thanks in advance,
Cheers
Latif
