I have a report where I want to display data graphically using a chart. My data source returns the required data as follows:

Make Model 2001 2002 2003
Ford Crown Vic 12 14 15
Ford Taurus 14 22 32
Ford Escort 2 4 24
Chevy Caprice 18 12 44
Chevy Corvette 9 14 15
Chevy Silverado 22 23 44

I want to be able to display each Make on a separate chart. I created the Chart and created a Make Header but when I display the data I get the same chart three time for each type. What am I doing wrong?
