Just in case you haven't updated in a while, I would do so since there was a fix included in yt 3.2.1 that might solve your problem.

https://bitbucket.org/yt_analysis/yt/pull-requests/1698/ensure-the-frb-is-va...

If you're already on yt 3.2.1 I'll take a closer look at this soon.

Hello there,

I'm trying to do a multipanel plot of projected density with titles in each axis and annotations but I couldn't figure out how to do it, could you please help me.

I'm using AxesGrid as in your example(

http://yt-project.org/doc/cookbook/complex_plots.html#multipanel-with-axes-l... )

...

however something is wrong. I'm sending my output image as a attached file.

My code is the following:

import yt import matplotlib.pyplot as plt import sys import numpy as np from mpl_toolkits.axes_grid1 import AxesGrid import matplotlib.colorbar as cb from matplotlib.colors import LogNorm

data=[] data.append(sys.argv[1]) data.append(sys.argv[2]) data.append(sys.argv[3]) data.append(sys.argv[4])

pf1=yt.load(data[0]) pf2=yt.load(data[1]) pf3=yt.load(data[2]) pf4=yt.load(data[3])

pfs=[] pfs.append(pf1) pfs.append(pf2) pfs.append(pf3) pfs.append(pf4)

fig=plt.figure() grid = AxesGrid(fig, (0.075,0.075,0.85,0.85),nrows_ncols = (2, 2),axes_pad = 1.0,label_mode = "all",share_all =

True,cbar_location="right",cbar_mode="single",cbar_size="5%",cbar_pad="5%",cbar_set_cax=True)

...

axe=['y','y','y','y'] field=['density','density','density','density'] colors=[] title=['100 Mpc/h box size', '75 Mpc/h box size','100 Mpc/h box size','50 Mpc/h box size']

for i in range(len(data)): p =yt.ProjectionPlot(pfs[i],axe[i],field[i],center='c',width=(25,'Mpc/h')) p.set_zlim('density',4.4601764879407653e-5,5.0e-2) p.annotate_timestamp(corner='upper_left', redshift=True,draw_inset_box=True) p.annotate_title(title[i]) plot=p.plots[field] plot.figure=fig plot.axes=grid[i].axes plot.cax=grid.cbar_axes[i] p._setup_plots()

fig.savefig('plot1_f.png',pdi=300)

Kind regards, -- Guido
