geom_hline() does not work: TypeError: unorderable types: float() > NoneType()

[Make42]

If I write

from ggplot import *
import matplotlib.pyplot as plt
plt.figure()
ggplot(aes(x='date_hour', y='pageviews'), data=pageviews) + \
    geom_point() +\
    geom_hline(yintercept=[10000])

from the documentation http://ggplot.yhathq.com/docs/geom_hline.html I get the error

Traceback (most recent call last):

    scaley = (yy < ymin) or (yy > ymax)
TypeError: unorderable types: float() > NoneType()

My ggplot is installed with anaconda on python 3.5 from conda-forge and it's version is 0.11.5. Installed with https://anaconda.org/conda-forge/ggplot

What do I do?

@Make42 the documentation is incorrect. See #545 and

ggpy/ggplot/geoms/geom_hline.py

Line 31 in 5957a4d

y = self.params.get('y')

. You should give geom_hline a parameter y, not yintercept

[Make42]

@kljensen Are you able to correct the documentation then? Or who is?

[kljensen]

@Make42 you can edit the gh-pages branch of this repo and submit a pull request

[vm-asd2015]

@kljensen Can you show me the file in gh-pages (or another branch/repo) that generates http://ggplot.yhathq.com/docs/geom_vline.html ?
