New issue 789: PhasePlot save missing string https://bitbucket.org/yt_analysis/yt/issue/789/phaseplot-save-missing-string
If I save the phase plot in another directory with:
pplot = PhasePlot(dd, "Density", "Temperature", ["Electron_Fraction"], weight_field=None)
the file name is "frames/_2d-Profile_Density_Temperature_Electron_Fraction.png"
if I just use
pplot.save() it will include the pf string as "HD1200_2d-Profile_Density_Temperature_Electron_Fraction.png" correctly.
So by specifying the folder it replaces the pf string. ProjectionPlot does not have the same issue. Annoying bug, but not critical.
