public class TransferX
extends AbstractTransferProxy

A transfer function that converts the normalized selected rectangle on the source graph into a normalized rectangle on the slave graph by keeping the x-selection, but widing the y-selection to the entire display space. Inparticular this means that the incoming view is transferred to user space with the source's UserCoordinates transform. We then keep the x-bounds and query the slave for its y-span. This y-span together with the x-bounds is now normalized using the slave's coordinate transform.

Method Detail

getAttachedView

protected Rectangle2D getAttachedView(Object src,
                                      Rectangle2D view,
                                      JViewportCanvas on)

Converts to a zommable rectangle if the source is a UserCoordinates instance and if the attached slave is a data canvas. If so, we keep the x-bounds from the selection's upper-left and lower-right corner and add the y-span from the slave. We re-transfer to normalized using the slave. If any process fails, we return null.
