Public Overloads Function FindMaxValue( _
   ByVal useValue As String _
) As DataPoint

Visual Basic (Usage)	Copy Code
Dim instance As DataPointCollection Dim useValue As String Dim value As DataPoint   value = instance.FindMaxValue(useValue)

public DataPoint FindMaxValue( 
   string useValue
)

Parameters

useValue

The point value to be examined (e.g. X, Y, Y2, etc.).

Which point value to use (X, Y1, Y2,...).

Return Value

The first DataPoint object in the DataPointCollection that has a maximum X or Y-value. If no data point is found (which will only occur if there are no points in the collection) then null will be returned.

The following sample returns the first data point that has a third Y-value (Y3) that is the series maximum, and we change the color of that point.

Visual Basic	Copy Code
Imports Dundas.Charting.WinControl ...     ' Find max data point of Y3 values     Dim maxPoint As DataPoint = Chart1.Series("Series1").Points.FindMaxValue("Y3")     ' Set color of this point     maxPoint.Color = Color.BlueViolet ...

C#	Copy Code
using Dundas.Charting.WinControl ...    // Find max data point of Y3 values    DataPoint maxPoint = Chart1.Series["Series1"].Points.FindMaxValue("Y3");        // Set color of this point    maxPoint.Color = Color.BlueViolet; ...

Returns the first data point in the collection that has a maximum X or Y-value (there may be more than one point with the maximum value).

This function definition starts the search at the beginning of the collection, and can only be used to locate the first data point in the collection that has a maximum value. To locate ALL data points in the collection that have a maximum X or Y-value use the definition that takes a startFromIndex parameter value.
