Saving and Restoring Plots

A plot consists of several components:

• The plot picture (that is, a graphic object).

• The current equation or equations (stored in the reserved variable EQ).

• The current plot parameters (stored in the reserved variable PPAR

and, in the case of three-dimensional plot types, VPAK).

• Flag settings that determine plotting and display options.

You have the option to save any or all of these plot components in a

variable so that you cair retrieve them later. Here are two useful

approaches:

• Save just the plot picture in a variable. This is a simple procedure (see

below) but each plot picture uses about one kilobyte of memory.

• Save the current EQ, PPAR, VPAR (if necessary), and flag settings in a

list. See “To save a reconstnictable version of the ciuTent plot” on page

10-7. The plot can be reconstructed by restoring each of these values

contained. (See “To reconstruct a plot from its stored version” on page

10-8.)

To save the current plot picture in a variable

1. While viewing the plot, press (STo^.

A copy of the plot is placed in history.

2. Press (CANCS) rmtil you return to histoiy.

3. Press (STO»).

4. Enter a name for the plot.

5. Press (HD.

In RPN mode: follow steps 1, 2, 4, and 3.
