New issue 789: PhasePlot save missing string https://bitbucket.org/yt_analysis/yt/issue/789/phaseplot-save-missing-string gsiisg: If I save the phase plot in another directory with: pplot = PhasePlot(dd, "Density", "Temperature", ["Electron_Fraction"], weight_field=None) pplot.save('frames/') 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.
