ZPrevious replots the graph using the window variables of the graph that
was displayed before you executed the last ZOOM instruction.
ZoomSto
ZoomSto immediately stores the current viewing window. The graph is
displayed, and the values of the current window variables are stored in
the user-defined ZOOM variables ZXmin, ZXmax, ZXscl, ZYmin, ZYmax,
ZYscl, and ZXres.
These variables apply to all graphing modes. For example, changing the
value of ZXmin in Func mode also changes it in Par mode.
