Report Builder bar chart with 3 bars and 3 conditions

Hello, How do I create a report using Report Builder that contains 3 bars, each one counting the number of artifacts that meet a certain condition, e.g., bar 1 counts the number of artifacts where the primary text contains "apples", bar 2 ... "oranges", and bar 3 ... "pears"? I am able to create a report with a chart with one bar on it very easily, but I cannot figure out how to add more bars with different conditions from the first bar. Thanks. Richard
