9.5. - zO# select filter line style
changes the line width or color of lines drawn using certain graphics filters. The effect of the command depends on the particular graphics-filter program, although most adhere to the conventions described at the end of this chapter.
z#No arguments are used. For
#,
enter an integer greater than
or equal to zero.
When selecting one or more line styles as part of
a string of plotting commands, insert the numbers in the string rather
than including them as arguments.
For instance,
z2alt1p uses
style 2 to draw the axes, labels and title, and style 1 to draw the
points.
The
z# command is comparable to the
select pen
command,
p #,
described in Chapter 7.
