zoom_rect - zoom a selection of the current graphic figure
zoom_rect is used to zoom a given rectangle of the current graphic figure: the rectangle(s) formed by the intersection of the given rectangle with the axes boxe(s) are zoomed, i.e. the rectangle(s) content are enlarged to fill the axes boxe(s). The selected rectangle for each axes is stored in the zoom_box property of associated the axes entity (see axes_properties ).
Without argument, the user is required to select the rectangle with the mouse. If specified, the rect argument should contain the coordinates ( using the current graphics scale) of two opposite corner of the rectangle.
The zoom_rect function corresponds to the Zoom menu.
