Setting the Window Variables
The graph screen window represents the portion of the
coordinate plane displayed on the graph screen. By setting
window variables, you can define the graph screen window
boundaries and other attributes.
xMin
,
xMax
,
yMin
, and
yMax
are the graph screen boundaries.
xScl
(x scale) is the number of units represented by the distance from one tick mark to the next
tick mark on the x-axis.
yScl
(y scale) is the number of units represented by the distance from one tick mark to the
next tick mark on the y-axis.
xRes
sets pixel resolution for function graphs only, using integers
1
through
8
.
At
xRes=1
(the default), functions are evaluated and graphed at each pixel on the x-axis.
At
xRes=8
, functions are evaluated and graphed at every eighth pixel along the x-axis.
To remove tick marks from
both axes, set
xScl=0
and
yScl=0
.
Small
xRes
values improve
graph resolution but may
cause the TI
-
86 to plot
graphs more slowly
.
