avplot popden, xtitle(,
size(huge)
)
We can modify the look of the existing
title without changing the text. For
example, we add the
size(huge)
option to make the existing title huge
in size. See
Options : Axis titles
(254)
and
Options : Textboxes
(303) for more
details.

rvfplot
Consider this residual-versus-fit plot.
We often hope to see an even
distribution of points around zero on
the
y
-axis. To help evaluate this
distribution, we might want to label the
y
-axis identically for the values above 0
and below 0.

Fitted values
rvfplot,
ylabel(-60(20)60, nogrid) yline(-20 20)
Here, we add the
ylabel()
option to
label the
y
−
60 to 60,
incrementing by 20, and suppress the
grid. Further, we use the
yline()
option to add a
-axis from
20.
For more information about labeling
and scaling axes, see
Options : Axis labels
(256) and
Options : Axis scales
(265).
