Detailed Description

2D widget for manipulating a XY plot

This class provides support for interactively manipulating the position, size, and orientation of a XY Plot. It listens to Left mouse events and mouse movement. It will change the cursor shape based on its location. If the cursor is over an edge of thea XY plot it will change the cursor shape to a resize edge shape. If the position of a XY plot is moved to be close to the center of one of the four edges of the viewport, then the XY plot will change its orientation to align with that edge. This orientation is sticky in that it will stay that orientation until the position is moved close to another edge.
