To pause while a graph is being drawn, press b; press

b again to resume plotting.
Press ^ to stop graphing. Press * to start over and plot

again.

 

When you press *, the Graph screen immediately displays

(instead of replotting) the previous function graph(s) if no

changes were made. If changes were made, the functions are

replotted.
The graph is replotted if you have:

• 

Changed a function.

• 

Selected or deselected a function.

• 

Changed the value of a variable in a selected function.

• 

Changed a 

 variable or a - g setting.

• 

Cleared drawings by selecting 

 (Chapter 10: Draw).

• 

Changed a stat plot definition (Chapter 6: Statistical

Plots).

 

Use ", !, $, and # to move the cursor around the Graph

screen. When you first display the graph, the cursor is in the

middle of the screen but is not visible. When you press a

cursor key, the cursor moves from that point and can be seen.

(Remember to use the - g 

 setting if you want

to see the (X,Y) coordinates at the bottom of the screen.)

 

Exploring a Function Graph with )

Pressing ) allows you to move the ! and " cursor keys

from one plotted point to another and displays the cursor

coordinates at the bottom of the screen (if 

is set). If

 (- g) is set, the expression being traced

appears in the top left corner.
