Conditionnal formula in a field

[LD1]

Hi everyone, 

I would like to apply a bar chart with the "variation 2023 vs 2022" into the field "2023":

The aim is to not display in the visual the variation but to apply it through the conditionnal formula (bar chart):

Thank you in advance for your help,

Léna
