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.
