I need to create a pie chart based on the total of the values in the cells, not 100% which is what it seems to be defaluting to - can that be done?

Example, I have two figures, 83 and 11. I need the chart to consist of two slices, one showing 83%, the other showing 11%.

Right now, my chart is showing 88% and 12%, assuming the end must be 100%.

Any thoughts? I scanned the charts forum but didn't see anything that was an obvious posting about this same issue.

Thanks!
