Remarks

The options provided by the NumericChartRangeControlClientRange class allow you to limit a chart client range manually, by specifying both the minimum and maximum axis value. This can be done via the NumericChartRangeControlClientRange.Min and NumericChartRangeControlClientRange.Max properties.

Note that the range of the numeric chart client is calculated automatically (the ChartRangeControlClientGridOptions.Auto property is set to true) by default. When you define the custom range, this resets the auto range calculation.

Examples

This example shows how to bind a numeric chart range control client to a System.Collections.Generic.List containing NumericItem objects.

In order to provide data to a chart numeric range control client, you need to access the ChartRangeControlClientDataProvider object using the ChartRangeControlClientBase.DataProvider property and assign a data source to the ChartRangeControlClientDataProvider.DataSource property.

Each NumericItem object contains Argument, Value and Series properties, to which a numeric chart range control client is bound via its ChartRangeControlClientDataProvider.ArgumentDataMember, ChartRangeControlClientDataProvider.ValueDataMember, and ChartRangeControlClientDataProvider.SeriesDataMember (optional) properties.

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