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.
