Graphing Creator Subform data in analytics

Graphing Creator Subform data in analytics

Hello,

I have a question on how to graph the data in a subform properly. I want to drill down the data based on one field in the subform such as the equipment name and I want that field to be displayed in the legend. But the name of the equipment is not a number value instead I am graphing values associated with that row in the subform; therefore the legend contains the name of the recorded values as opposed to the name of the equipment. 

Is there a way to graph number values in a subform row that correspond to the name of the row for that subform? The legend would correspond to the values for that row that are displayed. I hope that makes sense.
