# Example of plotting data and fitting data to an arbitrary
# function in gnuplot
# 
# The file gamma.dat contains the following points
#  0.0   0.00
#  0.2   1.77
#  0.4   4.80
#  0.6  13.06
#  0.8  34.49
#  1.0 100.00
#
# The next command plots the data points
#
plot "gamma.dat" with points
#
# Now define the arbitrary function to which we want to fit the data
#
F(x)=a*exp(b*x)
#
# Define a tolerance for the fit
#
FIT_LIMIT = 1e-12
#
# Now attempt to fit the data to the funtion
#
fit F(x) "gamma.dat" using 1:2 via a,b
#
# The above command should return the fit values for a and b.
# To place the fit line on your plot do the following...
#
replot F(x) with lines
#
# This should leave you with a nice plot on the screen.  To get this
# into a postscript form for plotting or turn in use the following
# sets of command.
set output "plot.ps"
set terminal postscript enhanced color landscape
replot
# This should leave a file called plot.ps in your directory for printing
# or inclusion into a paper.
