com.sas.servlet.tbeans.graphics.html.PieChart
public class PieChart
The PieChart TransformationBean is a servlet component that produces pie charts that support the visualization of multiple response variables. Pie charts use the size of pie slices to graphically represent the value of a statistic for a data range; they are useful for examining how the values of a variable contribute to the whole and for comparing the values of several variables.
Note. This class can be used to render server-side graphs in Java servlets or JavaServer Pages (JSP). The com.sas.graphics.components.PieChart class can be used to render client-side graphs in Java applications or applets. Both classes use the models in the com.sas.graphics.components package.
