When more than one function (or stat plot) is selected and
graphed, press $ and # to move the cursor from one function
graph to another.
The cursor movement is based on the order of the functions as
they appear in the Y= editor and not on the appearance of the
functions as graphed on the screen. (However, the TIN73 starts
with selected statistical plots first.)
The function number in the upper right corner of the display
changes as you move to the various graphs.
To quit ) mode, select another screen by pressing the
appropriate key, such as ' or (, or press - l
to return to the Home screen. Press : to stay on the
Graph screen.
Using QuickZoom
While tracing, you can press b to adjust the viewing
window. The cursor location then becomes the center of the
new viewing window, and the cursor remains in ) mode.
This is called
QuickZoom
. If you do a
QuickZoom
accidentally,
and you want to return to the zoom settings in the previous
window, select (
MEMORY 1:ZPrevious

Controlling the Increments of a Trace Controlling the Increments of a Trace
By assigning a specific value to @ X
(which is optional), you can
control the X coordinates of a trace. @ X
is a
WINDOW
value;
change it by pressing '.
The TIN73 automatically calculates
@ X
as:
@ X
=
(
Xmax
-
Xmin
)
94
If standard window values are set (
ZStandard
),
@ X = .21276595744681
. If you assign a value to @ X
, the values for
Xmin
and
Xmax
are adjusted automatically according to the
formula above.
