topN graph not aggregating on field

Hello wylie,

Thank you so much for the help! I'm trying to build a top N graph with percentages. Bar Chart editor doesn't quite work because it doesn't allow me to do division. I'm trying to sum total records and sum all "failed" records, and use failed records / all records to get a percentage.

Bar chart doesn't seem to do the summing... in case I'm missing anything. Any advice for that? Thanks!
