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. -Nathan On Sun, Sep 28, 2014 at 1:05 AM, John Regan wrote:

HI All,

Is there an easy way to access the x_field and the y_fields in the ProfilePlot function?

So for example

prof = ProfilePlot(sphere, "radius", "density")

print prof.x_field print prof.y_field[0]

I inserted a couple of hack functions into the ProfilePlot class to return the x_field and the .items() tuple but there is probably a better way?

Hi Nathan,

Thanks for that. I'll have a look at what helper functions would be useful as I use the ProfilePlot routine and I can issue a PR then. I think it would be worth updating the docs with info like you just sent me.

Again, please feel free to open a pull request.

Cheers, John
