【问题描述】:
如果我写
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])
从文档 http://ggplot.yhathq.com/docs/geom_hline.html 我得到错误
Traceback (most recent call last):

scaley = (yy < ymin) or (yy > ymax)
TypeError: unorderable types: float() > NoneType()
我的 ggplot 在 conda-forge 的 python 3.5 上安装了 anaconda,它的版本是 0.11.5。用https://anaconda.org/conda-forge/ggplot安装
我该怎么办?
