Is the problem that the plot not displaying correctly or is the issue with
the raw profile data?  ProfilePlot has a set_xlim method that might be
useful here.

If you have

profile
= yt.create_profile(my_disk,"cylindrical_r","density",weight_field="cell_mass")

it might be illustrative to look at profile.x, and profile['density'].  You
might also need to manually set the extrema for the profile by passing in
an extrema dictionary to create_profile.
