1: ZPrevious Uses the previous viewing window.
2: ZoomSto Stores the user-defined window.
3: ZoomRcl Recalls the user-defined window.
4: SetFactors... Changes Zoom In and Zoom Out factors.
ZPrevious replots the graph using the window variables of the
graph that was displayed before you executed the last
ZOOM
instruction.
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.
ZoomRcl graphs the selected functions in a user-defined
viewing window. The user-defined viewing window is
determined by the values stored with the
ZoomSto instruction.
The window variables are updated with the user-defined values,
and the graph is plotted.
