Error_y with different values in a grouped bar chart

Hello,

How can I set different error_y values for each bar?

Here you have an example, im filling an above and a below array with the values for each bar.

Forget it, i’ve just solved it doing some substractions.
The pen is now working as intented.
Sorry.

Could you share your solution possibly? I’m trying to do exactly the same thing but cannot figure it out. Thanks!
