Shows a date-time data within a range control’s viewport.
Namespace : DevExpress.Xpf.Charts.RangeControlClient
Assembly : DevExpress.Xpf.Charts.v25.2.dll

Public Class DateTimeChartRangeControlClient
Inherits ChartRangeControlClient
To display date-time data within a RangeControl, you need to assign a DateTimeChartRangeControlClient instance to the RangeControl.Client property.
This example demonstrates how to use the date-time chart client for a range control to display a chart with date-time data within the range control’s viewport.
In this example a date-time chart range control client is bound to a System.Collections.Generic.List containing DateTimeItem objects.
Each DateTimeItem object contains Argument and Value properties, to which a date-time chart range control client is bound via its ChartRangeControlClient.ArgumentDataMember and ChartRangeControlClient.ValueDataMember properties.
