Lesson 23: Plotting Several Functions
To plot several functions on the same display, you must enter a list of
functions in the Ef field of the Plot screen. The easiest approach is to
create and name each function and then use the Variable Browser to
select which group to plot. The following example uses functions that
were created and named for you by the TEACH command when you
executed 1t in Lesson 1.
Example: Gather the following functions into a list and store the list
in the Ei: field: ONE, TWO, THREE, and FOUR.
Step 1: In the main Plot screen, move the highlight to the Ei: field
and open the Variable Browser. Note when you access the
Variable Browser from within PLOT, it only displays objects
in the current directory that can be plotted. Move to the
EQNS directory, if necessary, and use the arrow keys to
highlight the ONE equation.
