Namespace: DevExpress.Xpf.Charts.RangeControlClient

Assembly: DevExpress.Xpf.Charts.v20.2.dll

Declaration

public class RangeControlClientLineView :
    RangeControlClientView

Remarks

To display the chart client line view within a range control, you need to assign a RangeControlClientLineView instance to the ChartRangeControlClient.View property.

ChartRangeClientLine

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.
