.NET Framework (current version)

Namespace:   System.Web.UI.DataVisualization.Charting
Assembly:  System.Web.DataVisualization (in System.Web.DataVisualization.dll)

public void DataBindY(
	params IEnumerable[] yValue
)

Parameters

yValue
Type: System.Collections.IEnumerable[]

One or more comma-separated IEnumerable<T> data sources.

This method binds the Y-value(s) of the data points in the collection to the first column of the specified data source(s).

To bind Y-values to a data source column that is not the first available column, use the DataBindY method.

You can bind several Y-values by specifying multiple data sources, using the yValue parameter. Note that the first available column in each data source will be used for each data point's successive Y-values. For example, the first column of the first IEnumerable<T> data source will be bound to the first Y-value of data points, the first column of the second IEnumerable<T> data source will be bound to the second Y-value of data points, and so forth.

If Y-values are not provided by the data source, or if the wrong number of values are provided, an exception will be thrown.

The following is a list of objects that you can use as the data source parameter:
