Use View ⇒ Zoom Out to shrink your plot in your window. This option is quite useful when you accidentally zoom in a little too far, and need to zoom back out. Each time you select View ⇒ Zoom Out the plot shrinks in size. Repeatedly zooming out will eventually shrink your plot down to just a small dot on the screen. If this happens, use View ⇒ Full View to restore the display to full size.
