Question

我试图在齐柏林飞艇中绘制一个散射矩阵，到目前为止还没有运气。其他图形类型效果很好。

%pyspark
import numpy as np
import pandas as pd
from pandas.plotting import scatter_matrix
import matplotlib.pyplot as plt

df = pd.DataFrame(np.random.randn(1000, 4), columns=['a', 'b', 'c', 'd'])

scatter_matrix(df, alpha=0.2, figsize=(6, 6), diagonal='kde')
#plt.show()

示例here和here启发了我

我只得到以下输出，但不显示任何内容

array([[<matplotlib.axes._subplots.AxesSubplot object at 0x7f553e4c6110>,
        <matplotlib.axes._subplots.AxesSubplot object at 0x7f553e459050>,
        <matplotlib.axes._subplots.AxesSubplot object at 0x7f5535b2ee10>,
        <matplotlib.axes._subplots.AxesSubplot object at 0x7f553e315090>],
       [<matplotlib.axes._subplots.AxesSubplot object at 0x7f553e459690>,
        <matplotlib.axes._subplots.AxesSubplot object at 0x7f5541ef4f10>,
        <matplotlib.axes._subplots.AxesSubplot object at 0x7f5541e87490>,
        <matplotlib.axes._subplots.AxesSubplot object at 0x7f553e27ae10>],
       [<matplotlib.axes._subplots.AxesSubplot object at 0x7f553e36f7d0>,
        <matplotlib.axes._subplots.AxesSubplot object at 0x7f553e36f890>,
        <matplotlib.axes._subplots.AxesSubplot object at 0x7f553e40b850>,
        <matplotlib.axes._subplots.AxesSubplot object at 0x7f553e3e07d0>],

        <matplotlib.axes._subplots.AxesSubplot object at 0x7f553538b5d0>,
        <matplotlib.axes._subplots.AxesSubplot object at 0x7f553565ab10>]],
      dtype=object)

编辑

当我取消注释plt.show时，什么也没有发生，并且该段落一直持续运行。

当我查看日志时，看到：
