To display the DRAW menu, press y [DRAW]. The TI-83’s
interpretation of these instructions depends on whether
you accessed the menu from the home screen or the
program editor or directly from a graph.
DRAW POINTS STO
1:ClrDraw Clears all drawn elements.
2:Line( Draws a line segment between 2 points.
3:Horizontal Draws a horizontal line.
4:Vertical Draws a vertical line.
5:Tangent( Draws a line segment tangent to a function.
6:DrawF Draws a function.
7:Shade( Shades an area between two functions.
8:DrawInv Draws the inverse of a function.
9:Circle( Draws a circle.
0:Text( Draws text on a graph screen.
A:Pen Activates the free-form drawing tool.
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.
