New issue 1256: OffAxisProjection Fails to find proper dataset limits https://bitbucket.org/yt_analysis/yt/issues/1256/offaxisprojection-fails-to-... Cameron Hummels: In trying to generate some OffAxisProjections from outside of the simulation domain, I've stumbled on some problems with auto-determination of field extrema. This simple script demonstrates: ``` #!python import yt ds = yt.load("IsolatedGalaxy/galaxy0030/galaxy0030") yt.OffAxisProjectionPlot(ds, [1., 1., 0.5], 'density', [0.5, 0.5, 0.5], 1.5, north_vector=[0., 0., 1.]).save() ``` yields this STDERR: ``` #!python yt : [INFO ] 2016-08-05 16:38:13,256 Parameters: current_time = 0.00600002000283 yt : [INFO ] 2016-08-05 16:38:13,256 Parameters: domain_dimensions = [32 32 32] yt : [INFO ] 2016-08-05 16:38:13,256 Parameters: domain_left_edge = [ 0. 0. 0.] yt : [INFO ] 2016-08-05 16:38:13,257 Parameters: domain_right_edge = [ 1. 1. 1.] yt : [INFO ] 2016-08-05 16:38:13,257 Parameters: cosmological_simulation = 0.0 ^MParsing Hierarchy : 0%| | 0/173 [00:00https://bitbucket.org/repo/BXbAb/images/2802526612-xDwRi6w.png) Interestingly, I don't get this problem with different datasets, or with different views of *this* dataset, so I'm not entirely sure what is going on. Here is the output of the same script using the `enzo_cosmology_plus/RD0009/RD0009` dataset:
