gnuplot demo script: linkedaxes.dem

gnuplot version gnuplot 5.2 patchlevel rc2
#
# Demo for non-linear linked axes. 
# In this example x2 is proportional to 1/x.
# X axis is X-ray energy in eV; x2 axis is wavelength in Angstroms.
#
# The scattering data are pulled from the web using the GET
# command, which is provided by the perl-libwww module.
# You could replace it with wget or some other download tool, or you
# could manually download the data first and then plot from the local copy.
#
# For more information on the plot itself see
