如何子类化matplotlib的Figure类? [英] How do I subclass matplotlib's figure class?

问题描述

我试图在我的图形中添加一些自定义行为和属性，但是在确定有效(和Pythonic)方法时遇到了麻烦.

I'm trying to add some custom behaviors and properties to my figures, but I'm having trouble deciding on an effective (and Pythonic) approach.

我的第一个冲动就是简单地将matplotlib.figure.Figure子类化，但是我不知道该怎么做:我通常会创建新的图形并以类似的方式开始绘图

My first impulse is to simply subclass matplotlib.figure.Figure but I can't figure out how to accomplish this: I generally create new figures and start my plotting with something like

fig, ax = matplotlib.pyplot.subplots()

，我不知道如何使用自定义Figure子类.

and I can't figure out how this would work with a custom Figure subclass.

如何以一种仍然可以让我使用上述方法的pyplot方法的方式来子类化Figure?子类化是获得与图形关联的自定义行为的正确方法吗?是更好的方法吗?

How can I subclass Figure in a way that still lets me use pyplot methods like the one above? Is subclassing even the right way to get custom behaviors associated with a figure? Are the better approaches?

推荐答案

subplots采用其他关键字参数，这些参数直接传递给figures()，其中之一是用于创建图形的类.

subplots takes additional keyword arguments that are passed directly to figures(), one of which is the class used to create the figures.

class MyFigure(Figure):
    pass

fig, ax = matplotlib.pyplot.subplots(FigureClass=MyFigure)
