Basic Function Graphing 326
@x and @y are the distances from the center of one pixel to the center of an adjoining
pixel.
ZoomStd Sets Window variables to their default values.
xmin =
L10 ymin = L10 xres = 2
xmax = 10 ymax = 10
xscl = 1 yscl = 1
ZoomTrig Sets Window variables to preset values that are often
appropriate for graphing trig functions. Centers the origin
and sets:
@x = p/24 (.130899... radians ymin = -4
or 7.5 degrees) ymax = 4
xscl =
p/2 (1.570796... radians yscl = 0.5
or 90 degrees)
ZoomInt
Lets you select a new center point, and then sets
@x and
@y to 1 and sets xscl and yscl to 10.
ZoomData Adjusts Window variables so that all selected stat plots are
in view.
ZoomFit Adjusts the viewing window to display the full range of
dependent variable values for the selected functions. In
function graphing, this maintains the current xmin and
xmax and adjusts ymin and ymax.
Memory Lets you store and recall Window variable settings so that
you can recreate a custom viewing window.
SetFactors Lets you set Zoom factors for ZoomIn and ZoomOut.
