matplotlib步骤功能中的线型 [英] Linestyle in matplotlib step function

问题描述

是否可以将matplotlib步骤功能中的线型设置为虚线，点线等?

Is it possible to set the linestyle in a matplotlib step function to dashed, dotted, etc.?

我尝试过:

step(x, linestyle='--'), 
step(x, '--')

但这没有帮助.

推荐答案

从mpl 1.3.0开始，此问题已在上游固定

As of mpl 1.3.0 this is fixed upstream

由于step似乎忽略了linestyle，因此您必须稍作调整.如果您查看step在下面的操作，它只是用于绘图的薄包装.

You have to come at it a bit sideways as step seems to ignore linestyle. If you look at what step is doing underneath, it is just a thin wrapper for plot.

您可以通过直接与plot交谈来做您想做的事情:

You can do what you want by talking to plot directly:

import matplotlib.pyplot as plt

plt.plot(range(5), range(5), linestyle='--', drawstyle='steps')
plt.plot(range(5), range(5)[::-1], linestyle=':', drawstyle='steps')
plt.xlim([-1, 5])
plt.ylim([-1, 5])

['steps', 'steps-pre', 'steps-mid', 'steps-post']是drawstyle的有效值，并控制绘制步骤的位置.

['steps', 'steps-pre', 'steps-mid', 'steps-post'] are the valid values for drawstyle and control where the step is drawn.

拉请求，我个人认为这是一个错误.

Pull request resulting from this question, I personally think this is a bug. [edit: this has been pulled into master and should show up in v1.3.0].
