Issue #838: OffAxisSlicePlot dosen't respect the unit of width (yt_analysis/yt)
by Stuart Mumford May 2, 2014

New issue 838: OffAxisSlicePlot dosen't respect the unit of width https://bitbucket.org/yt_analysis/yt/issue/838/offaxissliceplot-dosent-resp… Stuart Mumford: I tried to run the `aligned_cutting_plane.py` from the cook book and changing: ``` #!python p = yt.OffAxisSlicePlot(ds, L, "density", sp.center, (25, "kpc")) ``` to ``` #!python p = yt.OffAxisSlicePlot(ds, L, "density", sp.center, (25, "pc")) ``` only resulted in the axis label changing not the view on the data.
