:
zoom_rect funtion is used to perform a zoom inside a set of Axes Objects.
The h input argument specifies on which Axes the zoom will apply. If h is a Figure handle then the zoom will apply on its Axes children. If h is a Axes handle then the zoom will only apply to this handle. If h is not specified, then the zoom is performed on the current Figure.
If rect input argument is specified then the zoomed Axes zoom_box property is modified by the argument (see axes_properties). Its bounds along X and Y axis are replaced by rect. If rect is not specified zoom_rect is an interactive zoom. User is required to select a rectangle using the mouse. The new zoom_box property of zoomed axes are then computed by finding the intersections of the rectangle with their axes boxe.
