XYDiagram2D.DiagramToPoint(DateTime, TimeSpan, Axis2D, Axis2D) 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(
    DateTime argument,
    TimeSpan value,
    Axis2D axisX,
    Axis2D axisY
)

Parameters

Name Type Description
argument DateTime

The point’s argument.

value TimeSpan

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.

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.
