如何在Python中使用Matplotlib绘制步进函数? [英] How do I plot a step function with Matplotlib in Python?

问题描述

这应该很容易，但是我刚开始使用matplotlib和python玩弄.我可以做一条线或散点图，但是我不确定如何做一个简单的阶梯函数.非常感谢您的帮助.

This should be easy but I have just started toying with matplotlib and python. I can do a line or a scatter plot but i am not sure how to do a simple step function. Any help is much appreciated.

x = 1,2,3,4
y = 0.002871972681775004, 0.00514787917410944, 0.00863476098280219, 0.012003316194034325

推荐答案

似乎您要 step .

例如

import matplotlib.pyplot as plt

x = [1,2,3,4] 
y = [0.002871972681775004, 0.00514787917410944, 
     0.00863476098280219, 0.012003316194034325]

plt.step(x, y)
plt.show()
