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

问题描述

Pycharm不显示以下代码中的情节:

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()

发生的事情是，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.

在绘图所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. 我尝试将python.exe和pythonw.exe都用作解释器，并且结果相同.

...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sys_info:

This is my sys_info:

C:\pyzo2014a\pythonw.exe -u C:\Program Files (x86)\JetBrains\PyCharm Community Edition 3.4.1\helpers\pydev\pydevconsole.py 57315 57316

推荐答案

只需使用

plt.show()

此命令告诉系统在Pycharm中绘制图.

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