If you have the full or pro packages, there are several plots that you can use. If you have base, you will have to create your own from the X-Y Graph.
With the full and pro packages, you can use either the Radar Plot or the Polar Plot. On the Controls palette go to Graph then Controls. The are the first ones in either row. I prefer the Polar plot for its look, but it takes some conversion to get the data right.
You can use the example finder to show the Polar Plot demo and the Radar Plot demo.
I hope that this helps,
