Anyway to sort a bar chart by a column that I am not displaying?

[rgelb]

I have a bar chart with a Song as the Axis and Popularity as the Value.  I'd like to sort it by Potential value, but I don't want to display the Potential value.

Is there a way to do that?

I do not know any way to do that in the Service, in the Desktop on the Modeling tab there is the Sort By column that allows you to do this.
