About Pie Controls

The Pie control lets you create multidimensional pie charts in two- or three-dimensional views. You can use one, two, or three independent variables, and up to three response (dependent) variables. You can view one pie chart at a time, or multiple pie charts that are organized in a row or in a grid.

The simplest pie chart displays a two-dimensional view of a chart. The independent variable determines what slices are in the pie, and the response variable determines the size of each slice:

You can enhance the analysis by changing to a three-dimensional view of the chart, and also analyzing a second response variable, whose values determine the height of each slice:

If you add a second independent variable, a separate pie chart is displayed for each of that variable's values. The charts are organized in a row. If you add a third independent variable, its values are used to organize the charts into columns, effectively forming a grid of pie charts:
