Chapter 22
Programs for graphics manipulation
This chapter includes a number of examples showing how to use the
calculator's functions for manipulating graphics interactively or through the
use of programs. As in Chapter 21 we recommend using RPN mode and
setting system flag 117 to SOFT menu labels. « »
We introduce a variety of calculator graphic applications in Chapter 12.
The examples of Chapter 12 represent interactive production of graphics
using the calculator's pre-programmed input forms. It is also possible to use
graphs in your programs, for example, to complement numerical results with
graphics. To accomplish such tasks, we first introduce function in the PLOT
menu.

The PLOT menu

Commands for setting up and producing plots are available through the PLOT
menu. You can access the PLOT menu by using: 81.01
„°L@) M ODES @) M ENU@ @@MENU@.
The menu thus produced provides the user access to a variety of graphics
functions. For application in subsequent examples, let's user-define the C
(GRAPH) key to provide access to this menu as described below.

User-defined key for the PLOT menu

Enter the following keystrokes to determine whether you have any user-defined
keys already stored in your calculator: „°L@) M ODES @) @ KEYS@ @@RCLK@.
Unless you have user-defined some keys, you should get in return a list
containing an S, i.e., {S}. This indicates that the Standard keyboard is the
only key definition stored in your calculator.
