Gets or sets the name of the data field that contains the chart client's point values.
When you bind a numeric chart range control client to simple type objects (short, integer, long, double, decimal, float types, etc.), for example, to an array of simple objects, you do not need to use ChartRangeControlClient.ArgumentDataMember and ChartRangeControlClient.ValueDataMember properties. In this case, the numeric chart client automatically treats simple type objects' values as chart values. As a result, the data values are shown in the same order in which elements are added to the array.
Specify the ChartRangeControlClient.ArgumentDataMember property if you need to display numeric points sorted by arguments in the ascending order, for example, from the collection.
