Matplotlib pyplot putting two plots side by side
提问by JAbrams
Hi I'm trying to put two plots side by side with plt and have tried the recommendations here: Trying to position subplots next to each other
嗨，我正在尝试将两个图与 plt 并排放置，并尝试了这里的建议：尝试将子图放置在彼此相邻的位置
however I am plotting using the default capabilities from pandas by doing
但是我正在使用Pandas的默认功能进行绘图
myDataFrame.plot(kind='scatter' x='xcol', y='ycol')
so i can't do plt.subplot(2, 1, 2)as in myDataFrame.subplot(2,1,2)(obviously)
所以我不能做plt.subplot(2, 1, 2)，如myDataFrame.subplot(2,1,2)（显然）
and doing
和做
plt.subplot(1, 2, 1)
myDataFrame.plot(kind='scatter' x='xcol', y='ycol')
plt.subplot(1, 2, 2)
myDataFrame.plot(kind='scatter' x='xcol', y='ycol')
just adds two plots before the plot i want
只是在我想要的情节之前添加两个情节
any ideas how i can still use myDataframe.plot(kind='scatter')and put two of them side by side
任何想法我仍然可以使用myDataframe.plot(kind='scatter')并将其中两个并排放置

In case you are still looking for it, here is a minimal working answer for you (excluding imports)
如果您仍在寻找它，这里有一个最小的工作答案（不包括进口）
fig, ax = plt.subplots(ncols=2, figsize=(10,4))
df = pd.DataFrame([[5.1, 3.5, 0], [4.9, 3.0, 0], [7.0, 3.2, 1],
[6.4, 3.2, 1], [5.9, 3.0, 2], [7.1, 4.5, 2]],
columns=['X', 'Y', 'value'])
df.plot.scatter(x='X', y='Y', c='red', ax=ax[0])
df.plot.scatter(x='X', y='Y', c='red', ax=ax[1])
Output

It looks like DataFrame.plottakes an axargument for a pyplot axis https://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.plot.html.
Try:
它看起来像一个 pyplot 轴DataFrame.plot的ax参数https://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.plot.html。尝试：
ax = plt.subplot(1, 2, 1)
myDataFrame.plot(kind='scatter' x='xcol', y='ycol', ax=ax)
