Hello Everybody, first I want to thank for every time I got an answer when I write here, I really appreciate it. Now I am writing because I am using PlotCollection (As you can see my code) and I have some questions 1) the plot is coming in cm^3 and I want to change it to kpc^3 is there a way to change it? 2) I am attaching the plot can I change to dot or any different symbol and color? 3) why some plot come "empty"? and also I get this error message /Data has no positive values, and therefore can not be log-scaled./ ----- sphere = pf.h.sphere(c, (250., 'kpc')) # 250. levels = 8 #8 mi, ma = sphere.quantities["Extrema"]("Density")[0] contour_values, connected_sets = sphere.extract_connected_sets("Density", levels, mi, ma) for i in connected_sets: eb = connected_sets[i] print "level " + str(i) + " clmsp# " + str(len(eb)) for j in eb: obj = eb[j] com = obj.quantities["CenterOfMass"]() print com pc = PlotCollection(pf, com) pc.add_profile_object(obj, ["Density", "Temperature"],weight="CellMassMsun") # average T(rho) pc.add_profile_object(obj, ["Density", "CellVolume"], weight=None) # pc.add_profile_object(obj, ["Density", "CellMassMsun"], weight=None) # try: pc.save("sliceplot_300_"+str(i)+"_" +str(j)) except Exception, e: print e continue ----- Thank you in advance!!
