Public Overloads Function FindMinValue() As DataPoint

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

public DataPoint FindMinValue()

Return Value

The first DataPoint object in the DataPointCollection that has a first 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 Y1 value equal to the series' minimum Y1 value. We then change the color of that point.

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

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

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

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