如何在python中显示matplotlib图 [英] How to show matplotlib plots in python

问题描述

我确信matplotlib for python的配置正确，因为我已经用它绘制了一些数字.

I am sure the configuration of matplotlib for python is correct since I have used it to plot some figures.

但是今天它由于某种原因而停止工作.我用非常简单的代码进行了测试，例如:

But today it just stop working for some reason. I tested it with really simple code like:

import matplotlib.pyplot as plt
import numpy as np
x = np.arange(0, 5, 0.1)
y = np.sin(x)
plt.plot(x, y)

没有错误，但没有显示任何数字.

there's no error but just no figure shown up.

我正在Ubuntu上使用python 2.6，Eclipse

推荐答案

在matplotlib中，您有两个主要选择:

In matplotlib you have two main options:

1. 创建图并在最后绘制它们:

1. Create your plots and draw them at the end:

import matplotlib.pyplot as plt

plt.plot(x, y)
plt.plot(z, t)
plt.show()

创建图并在创建后立即绘制它们:

Create your plots and draw them as soon as they are created:

import matplotlib.pyplot as plt
from matplotlib import interactive
interactive(True)

plt.plot(x, y)
raw_input('press return to continue')

plt.plot(z, t)
raw_input('press return to end')
