New issue 725: off_axis_projection example gives blank image https://bitbucket.org/yt_analysis/yt/issue/725/off_axis_projection-example-g... Kacper Kowalik: Following receipe: ``` #!python from yt.mods import * pf = load("HiresIsolatedGalaxy/DD0044/DD0044") L = [1,1,0] # vector normal to cutting plane north_vector = [-1,1,0] W = [0.02, 0.02, 0.02] c = [0.53, 0.53, 0.53] N = 512 image = off_axis_projection(pf, c, L, W, N, "Density") write_image(na.log10(image), "%s_offaxis_projection.png" % pf) ``` produce blank image and fails on `log10`. This snippet is a part of `source/visualizing/plots.rst`. I think the problem is caused by `W` but haven't investigated this in details. Also `na` should be changed to `np` ;-) Responsible: ngoldbaum
