Setting a table
• Table setting allows you set how to input data for a table.
• Press
@
y
to enter the table
setting screen.
• The cursor is initially located at
Auto
,
showing the variable input method.
Auto: Automatically creates a table based on the graph equations and
given TableStart and TableStep values.
User: Displays a blank table. As you input values for variable columns,
table values are automatically calculated by the equation. Thus,
although TableStart and TableStep inputs can be made when
selecting User, set values will be ignored.

Auto

• TableStart is a start value of the variable in the table, and
TableStep is a step value of the variable. Both are numeric
values.
