[yt-users] ProfilePlot in YT-3.0

[Nathan Goldbaum]

Hi John,

ProfilePlot is a wrapper around the Profile1D class, which calculates and
stores the histograms.  To access the underlying data you need to access
the profile object via the profiles attribute of the ProfilePlot:

import yt
ds = yt.load('IsolatedGalaxy/galaxy0030/galaxy0030')
plot = yt.ProfilePlot(ds.all_data(), 'radius', 'density')
profile = plot.profiles[0]
print profile.x_field, profile.x
print profile.field_data.keys(), profile['density']

There are probably a number of ways that the current API can be improved to
make it more straightforward to access this data.  PRs along this front
would be very welcome, I think.
