Summary of FUNCTION plot operation

In this section we present information regarding the PLOT SETUP, PLOT-
FUNCTION, and PLOT WINDOW screens accessible through the left-shift key
combined with the soft-menu keys A through D. Based on the graphing
examples presented above, the procedure to follow to produce a FUNCTION
plot (i.e., one that plots one or more functions of the form Y = F(X)), is the
following:

„ô, simultaneously if in RPN mode: Access to the PLOT SETUP window.
If needed, change

TYPE

to

FUNCTION

, and enter the name of the independent

variable.
Settings:

Θ A check on

_Simult

means that if you have two or more plots in the same

graph, they will be plotted simultaneously when producing the graph.

Θ A check on

_Connect

means that the curve will be a continuous curve

rather than a set of individual points.

Θ A check on

_Pixels

means that the marks indicated by

H-Tick

and

V-

Tick

will be separated by that many pixels.

Θ The default value for both by

H-Tick

and

V-Tick

is 10.

Soft key menu options:

Θ Use @EDIT to edit functions of values in the selected field.
Θ Use @CHOOS to select the type of plot to use when the

Type:

field is

highlighted. For the current exercises, we want this field set to FUNCTION.

Θ Press the AXES soft menu key to select or deselect the plotting of axes in

the graph. If the option ‘plot axes’ is selected, a square dot will appear in
the key label:

@AXES . Absence of the square dot indicates that axes will

not be plotted in the graph.

Θ Use @ERASE to erase any graph currently existing in the graphics display

window.

Θ Use @DRAW to produce the graph according to the current contents of PPAR

for the equations listed in the PLOT-FUNCTION window.

Θ Press L to access the second set of soft menu keys in this screen.
Θ Use @RESET to reset any selected field to its default value.

Note: the soft menu keys

@EDIT and @CHOOS are not available at the same

time. One or the other will be selected depending on which input field is
highlighted.
