DataPointCollection.AddXY Method (Object, Object[])

.NET Framework (current version)
 

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

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

public int AddXY(
	object xValue,
	params object[] yValue
)

Parameters

xValue
Type: System.Object

The X value of the data point.

yValue
Type: System.Object[]

One or more comma-separated values that represent the Y-value(s) of the data point.

Return Value

Type: System.Int32

An integer value that represents the 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 YValueType property of the DataPointCollection object that this data belongs to; if too many Y-values are specified, an exception will be thrown.

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

If your data points do not need an X-value—that is, if you are creating non-scatter plots—use the AddY method instead
