DataPointCollection.AddY Method (Object[])

.NET Framework (current version)
 

Adds a DataPoint object to the end of the collection, with the specified Y-value(s).

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

public int AddY(
	params object[] yValue
)

Parameters

yValue
Type: System.Object[]

A comma-separated list of Y-value(s) of the DataPoint object added to the collection.

Return Value

Type: System.Int32

An integer that represents the location in zero-based index where the item was inserted into the collection.

This method adds one DataPoint object to the DataPointCollection; the data point is always added to the end of the collection.

You must provide at least one (1) Y-value, otherwise an exception will be thrown. This method also checks the ChartType property of the DataPoint object this data belongs to; if too many Y-values are specified, an exception will be thrown.

The X-value will always be set to zero (0), resulting in non-scatter plots. If you want the data points to use an X-value, call one of the AddXY methods instead.

In order for DateTime formatting to have an effect, a value must be a DateTime object.
