The TI-83 Plus Viewing Window
The viewing window is the portion of the coordinate plane defined by
Xmin , Xmax , Ymin , and Ymax . Xscl (X scale) defines the distance between
tick marks on the x-axis. Yscl (Y scale) defines the distance between tick
marks on the y-axis. To turn off tick marks, set Xscl=0 and Yscl=0 .

Displaying the Window Variables
To display the current window variable values, press p . The
window editor above and to the right shows the default values in Func
graphing mode and Radian angle mode. The window variables differ from
one graphing mode to another.
Xres sets pixel resolution ( 1 through 8 ) for function graphs only. The
default is 1 .

At Xres=1 , functions are evaluated and graphed at each pixel on the
x-axis.
