I need plot a function with dots and the standard deviation. This post has all I need, but I am using matplotlib 2.1.0 on Python 3.4.3 and it doesn't draw upper and lower lines of standard deviation. I mean standard deviation lines doesn't have horizontal lines in their extremes. Is there any way to draw those lines in the matplotlib version which I am using?

Adjust capsize= and capthick= arguments to the function errorbar()
