Bar chart sort issue

[cmano]

Dear all.

As you can see below i want to sort the values with descending order but the bar at right is bigger than the middle one 

Any suggestion?

   thank you.

Try using the sort by expression in descending order. You will have to uncheck the others.

I need to write something in expression?.

If yes what i should?

Thank you

[BrunPierre]

The same calculation under the expressions window.

Sort by expression

[cmano]

In this case?

 

[BrunPierre]

Perhaps use the expression that's always likely to give the maximum value for the sorting.

Also, promote that very expression to the first under the expressions windows.

Hope it helps.

Its dynamic.

This time i have 3 values the next month i will have more or less.

Again thank you for your help
