I am trying to plot a series of functions on the same graphs. The code seems to run ok, but there is no picture coming coming out. just simply

<matplotlib.figure.Figure at 0xeafea58>

如何解决?

推荐答案

在IPython控制台中，确保图形显示(不显式调用plt.show())的最佳方法是使用%matplotlib模式.如果正确安装了matplotlib，它将自动为您的系统选择合适的后端.

In the IPython console, the best way to make sure figures show up (without explicitly calling plt.show()) is to use %matplotlib mode. If matplotlib is installed correctly, it should automatically choose a suitable backend for your system.

例如:

In [1]: import matplotlib.pyplot as plt

In [2]: plt.plot([1, 2, 3])  # no plot shown!
Out[2]: [<matplotlib.lines.Line2D at 0x110eac898>]

In [3]: %matplotlib
Using matplotlib backend: MacOSX

In [4]: plt.plot([1, 2, 3])  # plot shown now
Out[4]: [<matplotlib.lines.Line2D at 0x112174400>]

每个会话中只需输入一次%matplotlib magic命令.

The %matplotlib magic command only needs to be entered once per session.
