XValues Property (XYLineSeries)

Visual Basic
C#

'Declaration
 
Public ReadOnly Property XValues As DoubleCollection

'Usage
 
Dim instance As XYLineSeries
Dim value As DoubleCollection
 
value = instance.XValues

public DoubleCollection XValues {get;}

If no x values are supplied then the indices of the data points will be used for the x values.

This example creates a chart control.
