The RegisterSummaryFunction method is intended to register custom summary functions within a chart control.

Also, you may remove all custom summary functions from the chart, and add all default functions to it by calling the ResetSummaryFunctions method.

Expanded Example

The following example demonstrates how to create a custom summary function, which returns an OHLC point calculated by the passed array of values. To accomplish this task, create a DevExpress.XtraCharts.SummaryFunction delegate and register it using the RegisterSummaryFunction method:
