TI-82 STATS interpretation of these instructions depends on
whether you accessed the menu from the home screen or the
program editor or directly from a graph.

The
DRAW instructions draw on top of graphs. Therefore,
before you use the
DRAW instructions, consider whether you
want to perform one or more of the following actions.
• Change the mode settings on the mode screen.
• Change the format settings on the format screen.
• Enter or edit functions in the
Y= editor.
• Select or deselect functions in the
Y= editor.
• Change the window variable values.
• Turn stat plots on or off.
• Clear existing drawings with
ClrDraw (page 8.4).
Note: If you draw on a graph and then perform any of the actions
listed above, the graph is replotted without the drawings when you
display the graph again.
You can use any DRAW menu instructions except DrawInv to
draw on
Func, Par, Pol, and Seq graphs. DrawInv is valid only
in
Func graphing. The coordinates for all DRAW instructions are
the display’s x-coordinate and y-coordinate values.
You can use most
DRAW menu and DRAW POINTS menu
instructions to draw directly on a graph, using the cursor to
identify the coordinates. You also can execute these instructions
from the home screen or from within a program. If a graph is not
displayed when you select a
DRAW menu instruction, the home
screen is displayed.
