Caption: Let's say we want to look only at a certain group of poll respondents and their opinions of McCain and Obama. In the second illustration, the software user has dragged the attribute "income" (not shown) outside the doughnut, then uses and drop-down menu and drags the icon "earn between $100,000 and $150,000 per year" into the center of the doughnut. Now the bar chart reflects only the opinions of respondents in that income group. Note how the overall favorable ratings of both candidates increase.
