Chapter 3: Function Graphing 85
ZFrac1/8
ZDecimal replots the functions immediately. It updates the window variables to preset values, as
shown below. These values set @
X and @Y equal to 1/8 and set the X and Y value of each pixel to
one decimal place.
ZFrac1/10
ZFrac1/10 replots the functions immediately. It updates the window variables to preset values, as
shown below. These values set @
X and @Y equal to 1/10 and set the X and Y value of each pixel to
one decimal place.
Using ZOOM MEMORY
ZOOM MEMORY Menu
To display the
ZOOM MEMORY menu, press q ~.
ZPrevious
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.
Xmin=L47/8
Xmax=47/8
Xscl=1
Ymin=L31/8
Ymax=31/8
Yscl=1
Xmin=
L47/10
Xmax=47/10
Xscl=1
Ymin=L31/10
Ymax=31/10
Yscl=1
