TimeSpanChartRangeControlClientRange Class

Contains the common settings that define the range displayed by a time-span chart client of the range control.

Namespace: DevExpress.XtraEditors

Assembly: DevExpress.XtraEditors.v23.1.dll

NuGet Package: DevExpress.Win.Navigation


public class TimeSpanChartRangeControlClientRange :

The following members return TimeSpanChartRangeControlClientRange objects:


The DateTimeChartRangeControlClientRange class provides options that allow you to limit a chart client range. Set the DateTimeChartRangeControlClientRange.Min and DateTimeChartRangeControlClientRange.Max properties to specify the minimum and maximum axis values.

The time-span chart client range is automatically calculated when the ChartRangeControlClientGridOptions.Auto property is set to true (default). When you define the custom range, this resets the auto range calculation.


This example demonstrates how to configure a range control with the time-span chart client to display a chart with time-span data in the range control’s background.

In order to provide data to a chart time-span range control client, access the ChartRangeControlClientDataProvider object using the ChartRangeControlClientBase.DataProvider property and assign a data source to the ChartRangeControlClientDataProvider.DataSource property. Then specify the required data fields via the ChartRangeControlClientDataProvider.ArgumentDataMember, ChartRangeControlClientDataProvider.ValueDataMember, and ChartRangeControlClientDataProvider.SeriesDataMember (optional) properties.

In the current example, a time-span chart client is bound to a simple data table containing three columns (“Argument”, “Value”, and “Series”).

In addition, this example shows how to customize chart client common settings (e.g., change the time-span range, customize template view and grid options).
