We can use different kinds of grid lines
for the major and minor axis labels. In
this example, we have a solid, darker
gray line for the major axis labels and a
lighter gray, short, dashed line for the
minor axis labels. We include the
grid
option to ensure that the grid is
displayed.

. This
section begins by using data on the S&P 500 from January 2, 2001, to December 31, 2001,
stored in the file
sp2001
. For simplicity, we will use
tradeday
on the
-axis, representing
the trading day of the year. For this section, we will use the
vg s2m
scheme.
