如何让函数在python中返回图形(使用matplotlib)? [英] How to have a function return a figure in python (using matplotlib)?

问题描述

假设我有一些数据，并且我想通过将其传递到自定义绘图函数(myplot())来创建此数据的绘图.我在myplot()中使用了matplotlib的模块.

Assume that I have some data, and I want to create a plot of this data by passing it to a custom plotting function (myplot()). I am using the matplotlib's modules in myplot().

当我调用此函数时，我希望myplot()将句柄返回到图形，而不希望绘图显示绘图.这是iPython的示例代码和输出.

I would like myplot() to return the handle to a figure, and not plot display the plot when I call this function. Here is a sample code and output from iPython.

对此我有两个问题:

1. 即使我分配了输出，为什么仍能看到一个图 myplot()转换为f?
2. 将myplot()的输出分配给变量时，我需要什么来抑制该图?

1. Why do I still see a plot, even though I am assigning the output of myplot() to f?
2. What do I need to supress this plot when I am assigning the output of myplot() to a variable?

推荐答案

使用

ipython notebook

而不是

ipython notebook --pylab=inline
