S t e p 3 :
Enter the list of checked fiinctions into the EQs field and set
a vertical display range of -4 to 4 (large enough to display
the “largest’’ function in the list). You must turn off the
AUTOSCALE feature if it is currently checked before you
can
sèe
your
V“VIEW.
Because
it
uses only the first function
in the
list
to
determine the
vertical scale, autoscaling
while plotting a list of functions can give inconvenient and
surprising results
and
is generally
not
recommended.

You may plot as many functions simultaneously as memory allows—as
long as they are all gathered together in a list. You may either build
this list from a group of already-created variables (as in the previous
example) or enter the list from scratch using the command line.
