ERROR: MethodError: no method matching expand_extrema!(::Plots.Axis, ::Vector{Matrix{Float64}})

Hi,
I want to plot a confidence interval, but unfourtunaly I am not able to do it. I got the following error message:
ERROR: MethodError: no method matching expand_extrema!(::Plots.Axis, ::Vector{Matrix{Float64}})

The my plot function looks like this:

“all_score_mean” and “all_score_std” look like this:

does anybody know how to solve the problem?
Thanks in advance!

you probably just need to remove the square brackets from all terms containing all_score_mean.

It would have been easier to test, if you provided quoted source code instead of screenshots.

Thanks for the quick reply and for your help! It worked! Thank you very much!!!
