ASPxClientRadarDiagram.PointToDiagram(x, y) Method
Converts the display coordinates into a diagram coordinates object.
#Declaration
PointToDiagram(
x: number,
y: number
): ASPxClientDiagramCoordinates
#Parameters
Name | Type | Description |
---|---|---|
x | number | The X-coordinate of a point (measured in pixels relative to the top left corner of a chart). |
y | number | The Y-coordinate of a point (measured in pixels relative to the top left corner of a chart). |
#Returns
Type | Description |
---|---|
ASPx |
An ASPx |
#Remarks
Use the PointToDiagram method, to convert screen coordinates of a point to the diagram coordinates (measured in axis units). For example, this allows you to determine what series or series point is being clicked by an end-user, and perform the required actions accordingly.
Note
This method works only if the Enable
property is set to true
. And, if you don’t need to convert display coordinates into diagram coordinates on the client side, leave the Enable
property disabled, to reduce the amount of the server-client traffic.
For the opposite conversion (of diagram coordinates to screen coordinates), use the ASPxClientRadarDiagram.DiagramToPoint method (with an overload appropriate to your axes’ scale types).
With the XY-Diagram type, use the similar ASPxClientXYDiagram2D.PointToDiagram and ASPxClientXYDiagram2D.DiagramToPoint methods.
