Question

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])

来自文档http://ggplot.yhathq.com/docs/geom_hline.html我收到了错误

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。已安装https://anaconda.org/conda-forge/ggplot

我该怎么办？

Answer 1

以下错误表示您将floats与None值进行比较。

TypeError: unorderable types: float() > NoneType()

您传递给ggplot(...)的数据可能包含None个值。

转储您要绘制的值。
删除None值。

了解问题：

当ggplot(...)尝试将点映射到渲染区域时，它会进行比较(yy < ymin) or (yy > ymax)。 yy，ymin或ymax可能是None。
