Hello again yt-users,
I'm trying to plot density from a FLASH simulation in 2D spherical. I assumed that a 'SlicePlot' would be the natural choice, slicing along axis '2'/'z'/'phi'.
pf = load('starwind_hdf5_plt_cnt_0000')
slc = SlicePlot(pf, 2, "density")
However, I get the error:
yt : [INFO ] 2014-06-23 16:31:42,631 xlim = -400000000000.000000 400000000000.000000

Any help would be greatly appreciated,
Thanks so much!
