Matplotlib Errorbar Caps Missing

Question

I\'m attempting to create a scatter plot with errorbars in matplotlib. The following is an example of what my code looks like:

import matplotlib.pyplot as pl         


        

Answer 1

It has to do with the rcParams in matplotlib. To solve it, add the following lines at the beginning of your script:

import matplotlib
matplotlib.rcParams.update({'errorbar.capsize': 2})

It also works with plt.bar().
