Property Value

Type	Description
ValueDataMemberCollection

The collection of the names of data fields that contain series point values.

Remarks

To populate the ChartView series with data, you can bind it to a data source. To do this, set the Data property of your series to a SeriesDataAdapter instance and specify this adapter’s properties:

DataSource — the data source for the chart.
ArgumentDataMember — the data source field that contains argument values. Each data point of a series requires one argument value.
ValueDataMembers — the collection of data source fields that contain data values for series points. The number of items in the collection depends upon the series type (see the Examples section below).

Example

These examples show how to create and configure the data adapter to populate ChartView series of different types with data.

For most series types supported by ChartView (besides financial, range bar and bubble charts), specify one ValueDataMember object with the Type set to Value :
For financial series (CandleStickSeries and StockSeries), specify four ValueDataMember objects with Type set to High , Low , Open , and Close :
For RangeBarSeries, specify two ValueDataMember objects with Type set to High and Low :
For BubbleSeries, specify two ValueDataMember objects with Type set to Value and Weight :
