Matplotlib错误栏

Question

If I run this code:

plt.scatter(n, y, marker ='^', s = 30, color = 'k')
plt.errorbar(n, y, yerr=yerror)
plt.ylim(ymin = 5, ymax = 20)

The resulting graph has a red line between the scatterplot. How do I prevent this line from appearing? Additionally, how might I add caps to the error bars?

I have tried

(_, caps, _) = plt.errorbar(n,y, yerr=yerror, capsize=5, elinewidth=3)

for cap in caps:
    cap.set_color('k')
    cap.set_markeredgewidth(3) 

and

plt.errorbar(n, y, yerr = yerror, ecolor = 'k', capsize = 5)

But neither has worked. There is clearly something fundamental I am missing about errorbars.

Answer 1

After further searching (almost immediately after I posted the question) I have found that adding

ls = 'none' 

within

plt.errorbar(n, y, yerr=yerror, ls = 'none')

will solve the issue.
