plot. You can define up to three plots.

functions as appropriate.
3. Define the stat plot.
4. Turn on the plots you want to display.

Xlist

Ylist
as
coordinate pairs, showing each point as a box (

(
+

Xlist
and
Ylist
must be the same length.
You can use the same list for
Xlist
and
Ylist
.
xyLine
is a scatter plot in which the data points are plotted
and connected in order of appearance in
Xlist
and
Ylist
.
You may want to use
