has several noteworthy features.
. Color coding by rows. he top row of Fig.
.
continues the color coding of the
top row of Fig.
.
. Each level of
comb
has its own color. he split of the upper
right-hand panel into individual boxes emphasizes the pattern within each level
of
comb
.
he bottom row of Fig.
.
continues the color coding of the bottom row of
Fig.
.
. he visible change in the
Npg
value for similarly colored boxes in the
let panel (
comb
within each
strain
) agrees with the direction of the slope of
the similarly colored trace lines in the right panel.
. x-axis labels. helet and right panels both have an x-axisthatitemizesthesame
levels of the interaction. hey differ in the sequence in which those levels are
presented.
. x-axisspacing. hisversion ofthe graph emphasizes the nesting of thecombina-
tions within strains (let-hand panels) by spacing the within-combination boxes
slightly closer than the between-combination boxes. he let-hand panels also
use color coding by strain. he nesting of strains within combinations (right-
hand panels) is shown purely by color coding by combination.
. Reading by columns. Each boxplot pair in the let-hand panel expands on the
difference in traces of means for the corresponding strain. Each trace in the
right-hand panel illustrates the difference in mean for the corresponding pair
of boxplots for the corresponding strain.
