# 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

pause -1 "Hit return for demonstration of automatic histogram creation"
set title "Histogram built from unsorted data by 'smooth frequency'"
set ylabel 'counts per bin'
set xlabel 'bins'
plot 'hemisphr.dat' u (floor($1*20)):(1) smooth frequency with histeps
unset xlabel
unset ylabel

pause -1 "Hit return for normal distribution function."
set title "Normal Distribution Function"
plot [-3:3][0:1] norm(x)

pause -1 "Hit return for inverse error function."
set title "Inverse Error Function"
plot [-1:1] inverf(x)

pause -1 "Hit return for inverse normal distribution function."
set title "Inverse Normal Distribution Function"
plot [0:1] invnorm(x)
