) As Integer

Visual Basic (Usage)	Copy Code
Dim instance As DataPointCollection Dim xValue As Object Dim yValue() As Object Dim value As Integer   value = instance.AddXY(xValue, yValue)

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

Parameters

xValue

The X-value of the DataPoint object added to the collection.

The X-value of the DataPoint object added to the collection.

X value of the data point.

yValue

The Y-value(s) of the DataPoint object added to the collection (one or more comma-separated values).
List of Y values of the data point.

Return Value

Returns an integer that represents the index where the item was inserted into the collection (0-based).

This method adds one data point to the DataPointCollection object, always adding it 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 Type property of the Series object this data belongs to, and if too many Y-values are specified an exception will be thrown.

For DateTime formatting to have an effect a value must be a DateTime object.

If your data points do not need an X-value (e.g. if you are creating non-scatter plots) then use the AddY method instead.
