Pycharm不显示情节 [英] Pycharm does not show plot

问题描述

Pycharm 不显示以下代码中的绘图:

Pycharm does not show plot from the following code:

import pandas as pd
import numpy as np
import matplotlib as plt

ts = pd.Series(np.random.randn(1000), index=pd.date_range('1/1/2000', periods=1000))

ts = ts.cumsum()    
ts.plot()

发生的情况是一个窗口出现了不到一秒钟，然后又消失了.

What happens is that a window appears for less than a second, and then disappears again.

在绘图按预期显示的相同代码上使用 Pyzo IEP IDE(使用相同的解释器).

Using the Pyzo IEP IDE (using same interpreter) on the same code the plot shows as expected.

...所以问题一定出在 Pycharm 上的某些设置上.我尝试使用 python.exe 和 pythonw.exe 作为解释器，结果相同.

...So the problem must be with some setting on Pycharm. I've tried using both python.exe and pythonw.exe as interpreter both with same results.

这是我的系统信息:

推荐答案

随便用

import matplotlib.pyplot as plt
plt.show()

此命令告诉系统在 Pycharm 中绘制绘图.

This command tells the system to draw the plot in Pycharm.

示例:

plt.imshow(img.reshape((28, 28)))
plt.show()
