How to: Bind a Numeric Chart Range Control Client to an Array of Simple Type Objects

  • 2 minutes to read

This example demonstrates how to set up a range control with the numeric chart client to display a chart with numeric data in the range control’s background.

Usually, in order to provide data to a chart numeric range control client, you need to specify a datasource using the ChartRangeControlClient.ItemsSource property and specify the required data fields via ChartRangeControlClient.ArgumentDataMember and ChartRangeControlClient.ValueDataMember properties (for more information, see the How to: Bind a Numeric Chart Range Control Client to a List of Custom Objects example). Note that when the ArgumentDataMember property is specified, chart points are sorted by arguments in the ascending order.

In the current example, a numeric chart client is bound to an array of integers using the ItemsSource property. In addition, you can bind a numeric chart client to other simple type objects (short, integer, long, double, decimal, float types , etc.). In this scenario the data values are shown in the same order in which elements have been added to the array.
