■T T r':k'
This determines the r e s o l u t i o n of the plot. It is the
horizontal distance (in units or pixels—see next
field) between two plotted points. Larger step-sizes
provide speedier plots, but show less detail, while
smaller step-sizes provide more detail, but take longer
to draw. The default step-size for F'unct ion is 0.1
units.
When checked, the step-size is interpreted to represent
pixels. When unchecked (default) the step-size is
interpreted to represent units.
Enter the tick-spacing that you want displayed on the
horizontal axis. It can be determined either in pixels
or units depending on the state of its FtLH'EL-S field
(see below). The default is one tick-mark every 10
pixels.
Enter the tick-spacing that you want displayed on the
vertical axis. It can be determined either in pixels or
units depending on the state of its P DUELS field (see
below). The default is one tick-mark every 10 pixels.
When checked (default), the tick-spacing in H-TICK
and '■/■-■TICK is interpreted to represent pixels. When
unchecked, the tick-spacing is interpreted to represent
units.

and move the cursor along the plot of the current function.
■ ® and m jump the cursor between functions when multiple
functions are plotted.
Special Notes
m Algebraic expressions in EQ=i may contain any number of variables.
However, all variables except the independent variable must evaluate
to a real number in order for EQs to be plotted. Otherwise, you will
get the Undefined Nane error message.
