how do you want to sort it?

In descending order

If you are using an Aggregate model with the chart then you can sort it by the Grouping field name. Don’t use the Alias field name, but the actual name of the field. E.g.

I can’t really see the name of the fields that you have as your x-axis on your chart, but if it’s a date field or number field. Then you will have to use the whole formatted name.  e.g.

Also, check out this link https://docs.skuid.com/v11.2.10/en/skuid/models/aggregate-model/

It will tell you how to sort an Aggregate model at the very bottom of the page.

Hope this helps!
