To generate a number table by assigning list values to
x
,
, or
t
1. Tap
O
and then [Graph Format] to display the Graph Format dialog box.
2. Tap [Special] tab, and then select a list option (list1 through list6 or a list variable created by you) for the
[Table Variable] item.
• By way of example, here we will select “list1”.
3. Tap [Set] to apply the settings and close the dialog box.
4. Tap
O
, [Window] and then [Stat Editor] to display the Stat Editor window.
5. In the list you selected in step 2 (list1 in this example), input the values you
want to assign to
x
,
, or
t
.
• For information about Stat Editor window operations, see Chapter 7.
6. On the Graph Editor window, input the function(s) you want to use for
number table creation, and select the check box(es) to the left of the
function(s) you want to use.
7. Tap the [Type] menu, and then select the type ([
y
=Type], [
r
=Type], or [ParamType]) of the function(s) you
want to use for number table creation.
8. Tap
#
to generate the number table and display it on the Table window.
u
To draw a graph using a number table
Perform either of the operations below.
Tap [Graph] - [G-Plot] or tap
!
.
• This will draw a graph that plots the coordinates in the number table.
Tap [Graph] - [G-Connect] or
$
.
• This graphs the expression used to create the number table and plots the
coordinates in the table.

3. Enter the name you want to give to the variable, and then tap [OK].
• This assigns the list of data you selected to a variable with the name you specified.
Showing Linked Displays of Number Table Coordinates and Graph Coordinates
(Link Trace)
With Link Trace, selecting a value in a number table created using a function causes a crosshair pointer (trace
pointer) to appear at the corresponding coordinates on the graph.

To create a number table of
y
= 3log(
x
+5), graph the values, and perform link trace
