Mmmmm You are using a rollup field as the X-axis, and it is not a numeric field, it’s a string type, so sorting criterium is different, You need to set a rule to copy the value from the rollup to a new numeric field
As X-axis, are the customer names, which are grouped by the diagram,
as Y axis, it is the economic result of many contracts for each customer, again calculated from the diagram,
the only thing I wanted to highlight is that each contract uses the complex formula / sum function, to add the sum of many orders.
I’ve tried entering the sum in an equation field and a numeric field, but the result doesn’t change.
Thanks anyway
Sometimes with the problem of sorting, this is because I use the connection field itself, and then the sorting will be the record-ID, not what is used as the display. Could this be?
