Public Overloads Function FindMaxValue() As DataPoint

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

public DataPoint FindMaxValue()

Return Value

The first DataPoint object in the DataPointCollection that has a maximum first 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 in the collection that has a first Y-value that is equal to the series' maximum Y1 value. We then change the color of that point.

Visual Basic	Copy Code
Imports Dundas.Charting.WebControl ...     ' Find point with maximum Y value and change color     Dim maxValuePoint As DataPoint = Chart1.Series("Series1").Points.FindMaxValue()     maxValuePoint.Color = Color.FromArgb(255, 128, 128) ...

C#	Copy Code
using Dundas.Charting.WebControl; ...    // Find point with maximum Y value and change color    DataPoint maxValuePoint = chart1.Series["Series1"].Points.FindMaxValue();    maxValuePoint.Color = Color.FromArgb(255, 128, 128); ...

Returns the first data point that has the largest first Y-value (there may be multiple points that have the same 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 with the maximum Y1 value. To locate ALL data points in the collection with the maximum Y1 value use the definition that takes a startFromIndex parameter value.

To examine a value other than the first Y-value (e.g. Y3, or third Y value) use a definition that takes has useValue parameter.
