This page contains properties about loci. It appears only when a locus is
selected. (See Locus, page 62, for more information about loci.)
# of Samples
Determines how many samples Sketchpad will plot
when displaying the locus. The greater the number
of samples, the more geometrically accurate the
depiction of the locus and the smoother its
appearance on the screen. However, the greater the
number of samples, the slower Sketchpad will be in
calculating and displaying the locus. You can
change between a higher and a lower number of
samples using Locus Properties depending on
whether accuracy or speed is more important.
Display
Determines how Sketchpad displays the locus of a
point. (This property is available only when a locus
of points is selected.) When continuous, Sketchpad
connects all of a locus’s sampled points into a curve.
When discrete, Sketchpad displays the locus’s
samples as individual points and does not connect
them.

Graph Properties
This page contains properties about graphs of functions. It appears only
when a function plot is selected. (See Plot Function, page 78, for more
information about function plots.)
# of Samples
Determines how many samples Sketchpad will plot
when displaying the graph of the function. The
greater the number of samples, the more accurate the
depiction of the function and the smoother its
appearance on the screen. However, the greater the
number of samples, the slower Sketchpad will be in
calculating and displaying the graph. You can
change between a higher and a lower number of
samples using Graph Properties depending on
whether accuracy or speed is more important.
The default number of
samples assigned to newly
constructed loci is
determined by Preferences
(see page 51).
The default number of
samples assigned to newly
constructed function plots is
determined by Preferences
(see page 51).
