I have two expressions that return two bars with the values of the planned sale and held. I need to bring the result of the variation between the two bars without adding another.
Go to the presentation tab and in the lower right corner select 'Add' next to the 'Text in Chart' box. Within that you can do your planned sales minus held sales to get a variance & display it anywhere on the chart you like. You will need to preceed your expression with an equal sign.
