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

Converts a point’s diagram coordinates into screen coordinates.

Namespace: DevExpress.XtraCharts

Assembly: DevExpress.XtraCharts.v24.1.dll

NuGet Package: DevExpress.Charts

Declaration

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

Parameters

Name Type Description
argument TimeSpan

The point’s argument.

value Double

The point’s value.

axisX Axis2D

An Axis2D descendant that specifies the point’s x-axis.

axisY Axis2D

An Axis2D descendant that specifies the point’s y-axis.

pane XYDiagramPaneBase

A ControlCoordinates object that contains information about the point’s screen coordinates, and its associated pane.

Returns

Type Description
ControlCoordinates

A ControlCoordinates object that contains information about the point’s screen coordinates, and its associated pane.

Remarks

Use the DiagramToPoint method, to convert a point’s diagram coordinates (measured in axis units) to the screen coordinates (from the top-left window corner in pixels). 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.
