Hi. I am doing a PhD atm and I have decided to take the plunge with gnuplot. I have fitted some data to an equation h(t)=ho+a(t-to)^b+kt, with a, to, b and k being fitting constants (empirical formulae describing creep behaviour of a compressed material with time). Does anybody know how I can: 1) make these constants come up so the specific equation comes up in the text describing the line? 2) make gnuplot save these constants in a dat or csv or whatever for future reference? Any help would be massively appreciated!
