XYDiagram2D.DiagramToPoint(String, Double, Axis2D, Axis2D, XYDiagramPaneBase) Method

Converts the diagram coordinates of a point into screen coordinates.

Namespace: DevExpress.XtraCharts

Assembly: DevExpress.XtraCharts.v20.1.dll

Declaration

public ControlCoordinates DiagramToPoint(
    string argument,
    double value,
    Axis2D axisX,
    Axis2D axisY,
    XYDiagramPaneBase pane
)
Public Function DiagramToPoint(
    argument As String,
    value As Double,
    axisX As Axis2D,
    axisY As Axis2D,
    pane As XYDiagramPaneBase
) As ControlCoordinates

Parameters

Name Type Description
argument String

A String value, specifying the point's argument.

value Double

A Double, specifying the point's value.

axisX Axis2D

An Axis2D descendant, specifying the point's X-axis.

axisY Axis2D

An Axis2D descendant, specifying the point's Y-axis.

pane XYDiagramPaneBase

An XYDiagramPaneBase descendant, specifying the point's pane.

Returns

Type Description
ControlCoordinates

A ControlCoordinates object, containing information about the point's screen coordinates, and its associated pane.

Remarks

Use the DiagramToPoint method, to convert diagram coordinates of a point (measured in axis units) to the screen coordinates. For example, calling this method in the ChartControl.CustomPaint event handler allows you to obtain screen coordinates of series points, and draw custom graphics onto your chart across them.

NOTE

For the opposite conversion (of screen coordinates to diagram coordinates), use the XYDiagram2D.PointToDiagram method.

With the Radar and Polar diagram types, use the similar RadarDiagram.PointToDiagram and RadarDiagram.DiagramToPoint methods.
