Public Function GetPositionFromAxis( _
   ByVal chartAreaName As String, _
   ByVal axis As AxisName, _
   ByVal axisValue As Double _
) As Double

Visual Basic (Usage)	Copy Code
Dim instance As ChartGraphics Dim chartAreaName As String Dim axis As AxisName Dim axisValue As Double Dim value As Double   value = instance.GetPositionFromAxis(chartAreaName, axis, axisValue)

public double GetPositionFromAxis( 
   string chartAreaName,
   AxisName axis,
   double axisValue
)

Parameters

chartAreaName

The name of the ChartArea object that owns the specified axis.
Chart Area Name

axis

An AxisName enum value that identifies the relevant axis.
Axis Name Enumeration

axisValue

The axis value that needs to be converted to a relative pixel value.
Value, which has to be converted to relative pixel position

Return Value

The converted axis value, in relative pixel coordinates.

This method takes a given axis value for a specified axis (that belongs to a specified ChartArea object) and returns the relative pixel value.

Note that this method only returns one value per axis type, so to determine the location of a point within the chart image this method needs to be called twice, once per relevant Axis object.

You can convert the relative value this returns to an absolute pixel value using the GetAbsolutePoint Method.

See the Chart Coordinate System topic for a detailed explanation concerning the Chart's coordinate system.

For an example of this method see the Custom Drawing Using the PostPaint Event topic.
