Dear All, I am trying to plot a multi plot of temperatures at different red-shifts with following script. from yt.mods import * # set up our namespace import matplotlib.colorbar as cb fig, axes, colorbars = get_multi_plot( 3, 1, colorbar='vertical', bw = 4) file1="/app/run/csarkar/surajit/simulation_shock/simulation5/RD00" file2="/RedshiftOutput00" list = [11,13,22] m=0 #for kk in range(20,37): for kk in list: fn_i=str(kk) fn=file1+fn_i+file2+fn_i # parameter file to load print fn pf = load(fn) # load data pc = PlotCollection(pf, center=[0.5,0.5,0.5]) # defaults to center at most dense point#dd = pf.h.all_data() p = pc.add_slice("Temperature", 1, figure = fig, axes = axes[0][m], use_colorbar=False) p.set_log_field(False) p.set_zlim(1e4,5e7) #p.set_cmap("jet")# a different colormap p.modify["contour"]("Density", ncont=9, plot_args = {'colors':'w'},clim=(5e-30,5e-25)) #p.modify["contour"]("Temperature", ncont=10, plot_args = {'colors':'k'},clim=(3e7,1e8)) pc.set_width(15, 'mpc') # change width of all plots in pc m=m+1 #pc.save("%s_p.png" % pf) # save all plots for p, cax in zip(pc.plots, colorbars): cbar = cb.Colorbar(cax, p.image, orientation='vertical') p.colorbar = cbar p._autoset_label() fig.savefig("Temperature_at_rd00_11,13,22" % pf) The problem is that I am getting the temperature in log scale, even-though I used p.set_log_field(False) in my script. Please suggest me how to get-rid of this problem. -- Reju Sam John
