I have to change the size of the markers in my plot (making them bigger). How is it possible to change the width of errorbars too? I'm using matplotlib. Thanks.

plot=ax.errorbar(x,y, yerr=[y1,y2], color='red', fmt='.', markersize='10', ecolor='red',capsize=4)

推荐答案

您可以通过在调用 errorbar(x,y,...) 时设置 elinewidth 属性来使错误栏变粗错误栏文档.但是误差条的长度是你的数据:你不能改变长度而不改变它所代表的错误.

You can make the error bar thicker by setting the elinewidth attribute in the call to errorbar(x,y,...) errorbar documentation. But the length of the error bar is your data: you can't change the length without changing the error that it represents.

import matplotlib.pyplot as plt

# define x,y, y1,y2 here ...

plt.figure()
plt.errorbar(x,y, yerr=[y1,y2], color='red', fmt='.', markersize='10', ecolor='red',capsize=4, elinewidth=2)
