                                                  SOURCE 
                                            
                                        
            In this example, you can see how to render and configure a pie chart with different patterns. The pie chart is a circular graphic ideal for displaying categories as a proportion or percentage of the whole. You can apply different patterns to the pie slices using the ApplyPattern property in the series and the PointRender event.
        
More information on the pie series can be found in this documentation section.
