I have posted an updated text file
qdrawsyntax.txt which begins with
a detailed discussion of using qdraw.mac
for plotting sets of data. My old version
was lacking information, in particular, about
the option pj(lw) for the pts(...) function,
which allows easy control of line width
and causes the discrete points to be joined
with straight lines.
Also upgraded is qdraw.mac with a function
pts_syntax() with the same extensive introduction
to the use of qdraw for plots of data sets of discrete
points.
