# 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.

 "steps.dat" title 'steps' with steps, \
 'steps.dat' title 'fsteps' with fsteps, \
