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

Converts the diagram coordinates of a point into screen coordinates.

Namespace: DevExpress.XtraCharts

Assembly: DevExpress.XtraCharts.v24.1.dll

NuGet Package: DevExpress.Charts

Declaration

C#

public ControlCoordinates DiagramToPoint(
    DateTime argument,
    double value,
    Axis2D axisX,
    Axis2D axisY,
    XYDiagramPaneBase pane
)

VB.NET

Public Function DiagramToPoint(
    argument As Date,
    value As Double,
    axisX As Axis2D,
    axisY As Axis2D,
    pane As XYDiagramPaneBase
) As ControlCoordinates

Parameters

Name	Type	Description
argument	DateTime	A DateTime 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.
