Class PlotZoom

java.lang.Object
  jsynoptic.builtin.PlotZoom

All Implemented Interfaces:

DiagramComponent.ContextualDrawing, DiagramSelectionListener

public class PlotZoom
extends java.lang.Object
implements DiagramComponent.ContextualDrawing, DiagramSelectionListener

This class performs the additional drawing required to perform some zooms on one or several selected plots Zoom box - Its location and size are defined thanks to mouse events received through the ContextualDrawing interface.When zoom defintion is over, on button 2 release, the rectangle coordinates are used to compute the zoom aplied to the selected plots. If there is one plot selected then the zoom concerns all the axes (even the secondary axes if thy exist). If there is more than a plot selected, the zoom is restricted to the axis with intersection with the zoom rectangle. In that case only one axis is changed but it is done on all the selected plots. - A red dashed rectangle is drawn. Zoom wheel - Its location and direction of rotation are defined thanks to mouse events received through the ContextualDrawing interface. Zoom wheel is performed on the selected plot that contains mouse position. Zoom whell concerns all the axes (even the secondary axes if thy exist). Translation * - The translation vector is defined thanks to mouse events received through the ContextualDrawing interface. The translation concerns all the axes and all the selected plots.
