# # This file will serve as the datafile used in demonstrating the
# # "plot with steps" option.   Here is a gnuplot input file
# # which uses "plot with steps", inverse error function, normal
# # distribution function, and the inverse normal distribution
# # function.
#
# set title "Compare steps, fsteps and histeps"
# plot [0:12][0:13] "steps.dat" notitle with points,  \
#  "steps.dat" title 'steps' with steps, \
#  'steps.dat' title 'fsteps' with fsteps, \
#  'steps.dat' title 'histeps' with histeps
