New issue 903: Plot.set_xlim Error using ProfilePlot.from_profiles
https://bitbucket.org/yt_analysis/yt/issue/903/plotset_xlim-error-using

Alan Kap:

import yt
from yt import derived_field
from yt.units import kpc
from matplotlib import pylab as plt
# Lists to hold profiles, labels, and plot specifications.
profiles = []
labels = []
center = [0.5,0.5,0.5]

@derived_field(name = "code_r", units = "")
def _code_r(field, data):
    return data["spherical_r"]/kpc/10
ran = [1,2,4,15]

for i in ran:
    qs = yt.load("../old_code/DD%4.4d/data%4.4d" % (i,i))
    ad = qs.sphere(center,1)
    profiles.append(yt.create_profile(ad, ["code_r"],
                                      fields=["HI_kph"],
                                      weight_field=None,
                                      accumulation=True))
    labels.append("old: file %d" % i)
plot = yt.ProfilePlot.from_profiles(profiles, labels=labels)
plot.set_xlim(1e-3, 1e5)
plot.save()

--> this gives me the error "ReferenceError: weakly-referenced object no longer exists"
