Anyone know how I can solve this? I have two customers, Customer A and Customer B in a table. They are each being rated in 6 categories. I am using a radar chart to show the ratings between the two customers. I want to be able to add more categories though if I have to. How can I accomplish this so that the chart will automatically reflect those changes? I automatically want the categories on the graph to appear or disappear if I add or delete them on the Excel sheet.
