The horizontal display range, with the minimum
horizontal value in the first field and maximum horizontal
value in the second field.
The vertical display range, with the minimum vertical
value in the first field and maximum vertical value in the
second field.
The smallest value of the independent variable that you
want plotted.
The greatest value of the independent variable that you
want plotted.
Determines the resolution of the plot. It is the horizontal
distance—in units or pixels—between two plotted points.
Larger step sizes provide speedier plots, but show less
detail. Smaller step sizes provide more detail but take
longer to draw. See also PIXELS below.
When this field is checked, the STEP value is measured in
pixels. Wlren imchecked—which is the default setting—
the step value is measured in units.
Resets the horizontal display range and the vertical
display range so that the plot fills the screen.
Choose this option by pressing
auto . The H-View and
V-View fields are recalculated.
Plot setup parameters
Type
EQ
Indep
The type of plot (in this case,
parametric).
The angle units field indicates the units in which angular
arguments are to be interpreted: degrees, radians, or
gradians.
The equations you want to plot. It defaults to the
equations listed on the Plot - Parametric screen but it can
be changed on the Plot Setup input form.
The name of the independent variable (usually
t
for
parametric plots).
