在matplotlib中，如何在图形的两边显示一个轴? [英] In matplotlib, how do you display an axis on both sides of the figure?

问题描述

我想用matplotlib画一个图，图的两边都有轴，类似于这个图(颜色与本题无关):

I want to draw a plot with matplotlib with axis on both sides of the plot, similar to this plot (the color is irrelevant to this question):

我怎样才能用 matplotlib 做到这一点?

How can I do this with matplotlib?

注意:与示例图中显示的相反，我希望两个轴完全相同，并且只想显示一个图.添加两个轴只是为了让图表更容易阅读.

Note: contrary to what is shown in the example graph, I want the two axis to be exactly the same, and want to show only one graph. Adding the two axis is only to make reading the graph easier.

推荐答案

在线文档中有几个相关示例:

There are a couple of relevant examples in the online documentation:

• 两个比例(似乎完全符合您的要求)
• 双华氏度和摄氏温度

• Two Scales (seems to do exactly what you're asking for)
• Dual Fahrenheit and Celsius
