of the following before drawing on a graph:
¦
Change the mode settings.
¦
Enter or edit functions in the
Y=
list.
¦
Select or deselect functions in the
Y=
list.
¦
Change Window variable values.

Turn
STAT PLOTS

Draw operations can draw on
FUNC
and
PARAM
graphs. The
coordinates for all Draw instructions are always the
X-coordinate and Y-coordinate values of the display.
You can use most of the operations from the
DRAW DRAW
and
DRAW POINTS
menus to draw directly on a graph, using
the cursor to identify coordinates; or you can execute these
instructions from the Home screen or a program.
