Demo Area Move

This demo plots a simple figure and a small rectangle (gray) area. The position of the area can be interactively moved and resized interactively (in a standard "windows" way). When the area is double clicked, the figure is zoomed according the area. The double click outside the area resizes the figure into original size. According this demo can be modify others graphical codes, when more precise control of selected area then standard MATLAB zoom is required.
