7-4 Draw Operations
While a graph is displayed, LINE( lets you use the cursor to define a line on the
graph. If a graph is not displayed, the instruction is copied to the Home screen.
To define a line directly on a graph:
1. When a graph is displayed, select LINE( from the
DRAW DRAW menu (item 2).
2. Position the cursor at the beginning point of the line you
want to draw. Press ¸.
3. Move the cursor to the end point of the line you want to
draw. The line is displayed as you move the cursor. Press
¸.
To continue to draw lines, repeat steps 2 and 3. To cancel
LINE(, press M.
LINE( (DRAW DRAW, item 2) draws a line between the
coordinates (X1,Y1) and (X2,Y2). The values may be entered
as expressions.
LINE(X1,Y1,X2,Y2)
For example, enter LINE(0,0,6,9) on the Home screen, and
then press ¸.
