[yt-users] data_source=region

[Shankar Agarwal]

Hi,

http://yt-project.org/doc/cookbook/complex_plots.html#thin-slice-projections

Is it possible to create a thin slice projection of particles (instead of
density)?


I tried the following three methods but get errors:

1. p = yt.ParticlePlot(ds, 2, ['particle_mass'], data_source=region)

TypeError: __init__() got multiple values for keyword argument 'data_source'


2. p = yt.ParticleProjectionPlot(ds, 2, ['particle_mass'],
data_source=region)

finfo = self.ds._get_field_info("unknown", fname)


3. p = yt.ProjectionPlot(ds, 2, ['particle_mass'], data_source=region)

line 1429, in __init__
    field_parameters = field_parameters, method = method)

line 253, in __init__
    field = self._determine_fields(ensure_list(field))
