[yt-users] Unable to set log scale in Phase plot.

Dear all, I am trying to make a phase plot using YT 2.6, with the following line. *plot = PhasePlot(my_sphere, "Density**", "**Temperature* *","CellMassMsun",weight_field=None,x_log=1,y_log=1).save()* but it is giving me the following error. *plot = PhasePlot(my_sphere, "MachNumber", "CRFractionPreCR","CellMassMsun",weight_field=None,x_log=1,y_log=1).save()* *TypeError: __init__() got an unexpected keyword argument 'x_log'* I also tried with x_log=True.Still the same error. What could be the problem? How to make both x and y in log scale? And also I would like to know is it possible to fix x and y range in phase plot? Thank you. -- Reju Sam John
