Depending on the chart, you should be able to choose "Display: Percent of" for the way the chart displays. I know this is available for pie charts (we use it), but I can't guarantee is exists for other charts (such as bar or columns).
You can also display a "%" sign for report highlights, if you choose to go that route instead. If you choose "Summary Type: Other" and "Field Type: Text", you can use two variables to capture data points, then use "ToString((var1/var2),"0.0%")" in the Formula Options to control the display.
