The prompt for outlier points is
x=
, except when the outlier is the
maximum point (
maxX
) or the minimum point (
minX
). When outliers exist,
the end of each whisker will display
x=
. When no outliers exist,
minX
and
maxX
are the prompts for the end of each whisker.
Q1
,
Med
(median), and
Q3
define the box.
Box plots are plotted with respect to
Xmin
and
Xmax
, but ignore
Ymin
and
Ymax
. When two box plots are plotted, the first one plots at the top of the
screen and the second plots in the middle. When three are plotted, the
first one plots at the top, the second in the middle, and the third at the
bottom.
