Public Overloads Function FindMinValue( _
   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.FindMinValue(useValue)

public DataPoint FindMinValue( 
   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 an X or Y-value equal to the series' minimum. 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 minimum, and we change the color of that point.

Visual Basic	Copy Code
Imports Dundas.Charting.WebControl ...     'Find data point with the smallest third Y value     Dim myPoint As DataPoint = Chart1.Series("Series1").Points.FindMinValue("Y3")     'Change color of this point     myPoint.Color = Color.BlueViolet

C#	Copy Code
using Dundas.Charting.WebControl; ...    // Find data point with the smallest third Y value.    DataPoint myPoint = Chart1.Series["Series1"].Points.FindMinValue("Y3");        // Change color of this point.    myPoint.Color = Color.BlueViolet;     ...

Returns the first data point in the collection that has an X or Y-value that is equal to the series minimum 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 the minimum value. To locate ALL data points in the collection that have the minimum X or Y-value use the definition that takes a startFromIndex parameter value.
