Mean + errorbar causes ValueError: Buffer dtype mismatch

[HenrikEckermann]

Hey Hassan,

I ran into an error and I wonder if the plot is affected or not (since I get the output but also several error lines. I cannot figure out what is wrong here. Can you explain to me what is the problem or whether I made a mistake? Here is the gist

I use plotnine a lot. Thanks for all the effort!
