Hi @JohannesENS
please find attached and run the script in the table.
one way of doing this is by introducing a new column with the formula :"min diameter / mm"n + :range

now you set the min diameter and the max diameter together on the Y axis. then you choose bars and select the range option

let us know if it worked,
