How to display values both as real values and as percentages in a Pie chart's legend

This example demonstrates how you can force a pie chart's legend to display point values both as percentages and as real values.

First, make sure that the Series.LegendPointOptions.PercentOptions.ValueAsPercent property is enabled. Then, set the Series.LegendPointOptions.PointView property to Values. And, handle the chart's CustomDrawSeriesPoint event in the way shown in this example.

UPDATE: In the latest version it is possible to remove the CustomDrawSeriesPoint event handler and specify a required pattern using the Series -> LegendTextPattern property.
