Enter the name of the independent variable.
Enter the smallest value of the independent variable
that you want p l o t t e d . Plotting range for Parametric
plots are usually different than display range (see page
24-3).
Enter the largest value of the independent variable
that you want p l o t t e d . Plotting range can be different
than display range (see page 24-3).

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. The default step-size
for P.ar.ai'iet r i c: is an interval equal to j-f^th of the
difference between the Lu and HIGH values in the
plotting range (in units).
When checked, the step-size is interpreted to represent
pixels. When unchecked (default) the step-size is
interpreted to represent units.

TRACE Mode
■ s and © move the cursor along the plot of the current function,
a moves the cursor to the next lower value of the independent
variable and © moves the cursor to the next higher value of the
independent variable. This may result in directional movement
counter to the “direction” implied by the arrow' keys. A parametric
plot can be traced through an unlimited range of the independent
variable so you will be able to press © or a indefinitely in
TRACE mode, even beyond the plotted interval.
■ ® and jump the cursor between functions when multiple
functions are plotted.
