Using Zoom Operations
The zoom operations in the PICTURE environment let you look at a
particular region of the plot in more detail (by zooming in) or look at
more of the plot than is currently displayed (by zooming out).
A z o o m , or zoom operation, redraws the current plot by computing
new display parameters. Zooms are a shortcut for the process of
returning to the PLOT application, changing the values of the display
parameters, and redrawing the plot. Note that not all plot types make
use of zoom.
