GRAPHING FUNCTIONS
10. Selecting a Line Type for a Graph
• The calculator has five kinds of lines (Solid line (–), Dotted line (…), Bold line ( ),
Locus ( ), Dot ( )) for drawing graphs.
• The type of line can be selected on the DRAW menu.
It is possible to set a desired line type for equations in the different graph coordinate
systems (four kinds in total).
• To select a line type, do the following.
1. Press Ï,
, D. (The menu [D LINE] allows
you to set a desired line type.)
2. Press ®.
As shown in the figures below, a list containing the equation
number in each coordinate system and line type will appear
on the screen.

* The highlighted part on the screen expresses the current line type setting.
* The cursor flashes on the solid line of the first line (top of the screen).
* In the rectangular coordinate system, equations may exist on two pages. A

is
displayed at the left of the equation on the bottom line of the screen. (To show Y8, Y9 and Y0,
press Ï ≥ or press ≥… to move the cursor sequentially.)
* The initial line type is a solid line (–).
<Example>
To set Y1: Bold line, Y2: Dotted line, and Y3: Locus line in the rectangular coordinate
system.
