Display all items when there is a zero value with Pie Chart
I'm comparing 2 months of data and I want both pie charts to display the same legends. I also need both pie charts to use the same colours for the same items. Right now when I compare a chart with 2 items to one that has 1 item, the colours don't match. Both chart's item 1 are the same colour however item 1 on the second chart should match item 2 on the first chart.
