A string value that represents the data point values to be sorted. Possible values are: "X", "Y", "Y2", "Y3", "AxisLabel", etc. 

Note:  If X-values are of type string, they are stored in the AxisLabel,  this should be specified instead of "X"

Syntax

Visual Basic (Declaration)  
Public Overloads Sub Sort( _
   ByVal order As PointsSortOrder, _
   ByVal sortBy As String, _
   ByVal series As Series _
)
Visual Basic (Usage) Copy Code
Dim instance As DataManipulator
Dim order As PointsSortOrder
Dim sortBy As String
Dim series As Series
 
instance.Sort(order, sortBy, series)
C#  
public void Sort( 
   PointsSortOrder order,
   string sortBy,
   Series series
)

Parameters

order
A PointsSortOrder enumeration value that determines if the sort is ascending or descending.
Sorting order.
sortBy

A string value that represents the data point values to be sorted. Possible values are: "X", "Y", "Y2", "Y3", "AxisLabel", etc.

series

Series to sort.

Example

Perform an ascending sort on a series named "Series1" before data is displayed by the chart. We will assume a bubble chart is being displayed, and will sort the data based on the second Y-value ("Y2").
Visual Basic Copy Code
Imports Dundas.Charting.WebControl
  ...

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    Chart1.DataManipulator.Sort(PointsSortOrder.Ascending, "Y2", Chart1.Series("Series1"))
End Sub
C# Copy Code
using Dundas.Charting.WebControl;
 ...

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs)
{
   Chart1.DataManipulator.Sort(PointsSortOrder.Ascending, "Y2", Chart1.Series["Series1"]);
}

Remarks

This method performs an ascending or descending sort on a series' data points, and is based on the value that is set by the sortBy parameter (e.g. "X", "AxisLabel", "Y", "Y1", etc. .

To sort points using a custom sort routine or to sort more than one series per function call use another definition of this overloaded method.
