Pie charts and trying to understand them

Hello. I have been using pie charts, and I understand how to display something such as a pie chart of different users visits to a page, by doing a search. However I want to display something where all the values come from the same database. For example

In this image I have a few colors, all in the same entry, however the pie chart will only let me display one of the colors. How can I select multiple “current points” instead of just when for instances where the data all within the same entry? Or is there any way of doing this? Thanks!
