Pie and doughnut series views are intended to compare the percentage values of different point arguments in the same series. These charts may be useful to determine the most significant point value in the series, as well as the least significant. To see the entire list of available pie/doughnut views or to switch your current view to another, please use the View Type combo-box on the top of this demo.
In this demo's options you can choose whether or not it is necessary to show series labels (Show Labels), whether they display absolute values or percents (Values As Percent) and adjust their position (Label Position).
Also, you can select what pie slices should be expanded. For this, use the Exploded Points option.
