Error bars problem

hello everybody,

I am trying to apply the error bars automatically to a big number of graphs.
I start selecting the already done histogram graph, by clicking shift and error bars > after moving to the desired values (I moved the “mask” that the program create based on Automatic detection with the command Below), but when I press Set error bars the graph has default error bars without applying the selected values. What I am doing wrong?
And thanks to Daniel, this toolbox is going to make my life easier than before,

EDIT: I got it!
My data setting was a bit tricky, but I would like to ask to solve my situation.
Like the images show

I solve, it was the fault of my tricky data setting.
thank you!

PS I am not able to delet the post :neutral_face:

No problem, glad you solved it!
