DateTimeChartRangeControlClient Class

Shows a date-time data within a range control’s viewport.

Namespace: DevExpress.Xpf.Charts.RangeControlClient

Assembly: DevExpress.Xpf.Charts.v23.2.dll

NuGet Package: DevExpress.Wpf.Charts

Declaration

C#
VB.NET

public class DateTimeChartRangeControlClient :
    ChartRangeControlClient

Public Class DateTimeChartRangeControlClient
    Inherits ChartRangeControlClient

Remarks

To display date-time data within a RangeControl, you need to assign a DateTimeChartRangeControlClient instance to the RangeControl.Client property.

DateTimeChartRangeControlClient

Example

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.
