# gnuplot input file for dealing with quarterly data, as used by
# economists.  Allin Cottrell, May 1999.
# 
# Usage: within gnuplot, 
#
#      call "plotq.gp" "<datafile>" "<plot params>" {<maxtics>}
#
# e.g. call "plotq.gp" "econ.dat" "using 1:2 w l" 12
#
# The last param is optional and defaults to 12: it represents
# the maximum number of time-axis tics that should be labeled.
