[yt-users] change size of phase plot

Hi John (and all users!),

Thanks, this definitely worked!  Now I am trying to make my axes look a bit
nicer.  I would like to change my y-axis label and rotate my x-axis
ticklabels by 45 degrees or only print every other ticklabel.  I tried to
use the directions from the SlicePlot example,
http://yt-project.org/docs/dev/cookbook/simple_plots.html#showing-and-hiding-axes-labels-and-colorbars,


plot =
PhasePlot(tracerp25,"Density","z-velocity",["CellMassMsun"],weight_field=None,fontsize=13)#,x_bounds=[3e-28,5e-23],y_bounds=[-7e7,1.2e8])
plot.set_log("Density",True)
plot.set_log("z-velocity",False)
plot.set_zlim("CellMassMsun",1e4,1e9)
plot.set_figure_size(3)

ax = plot.plots['z-velocity'].axes
ax.set_ylabel(r'z-velocity (10$8$ cm/s)')
for label in ax.xaxis.get_ticklabels():
    label.set_rotation(45)

plot.save()

but get an error message:

ax = plot.plots['z-velocity'].axes
KeyError: 'z-velocity'

I get the same error if I use 'Density' on that line instead.

Thanks in advance,

Stephanie
