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.
