	Commonly available graphing routines that spring to mind include
gnuplot (available via ftp from lots of places) and CURVY from the CCP4
crystallographic package. Either one will plot nice axes, etc, and take
the data points from a simple ascii file.  CURVY has the annoying feature
for this particular case that it won't invert the x axis (which gives
a "backwards" Luzzati plot) but otherwise works fine.
