Chart Help

What field do I select from my table and where do I place them on the sample
graph in order to get a pie chart showing the correct information?


Details:
I'm trying to insert a chart into a report. Each page of the report is for
a different model name and then breaks down the model into parts:

REPORT:
Model 1
section a=25% section b=30% section c=45% ....

I would like a pie chart to represent the way each model is broken down (one
slice=section a, one slice=section b....)

Here is the table I'm trying to base the charts off of:
section a section b section c
Model 1 25 30 45
Model 2 ..................
