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

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.
