Follow-up Comment #4, sr #3210 (project relax): Thank you! To answer comment #1, yes, this is similar to the currently generated 'intensities.agr' file, except that the plotted curve is that of the fitted curve. I think the current generated 'intensities.agr' contains all the spin fitting in the project (at least for the results I get now). I'm not sure how to use Grace to plot a function (fitting curve) as I rarely use it. Do you know whether Grace can plot a function curve? _______________________________________________________ Reply to this item at: <http://gna.org/support/?3210> _______________________________________________ Message sent via/by Gna! http://gna.org/
