My son is doing physics coursework, and has a set of figures plotting voltage against resistance. He's used Qtiplot to draw a graph of the resulting curve, but does anybody know of any software which would allow this line to be extrapolated to show likely resistance for a given level of voltage - ie go beyond the actual data from the experiment to show what might happen if the experiment had been extended? It may be that Qtiplot can do this, but I can't find out how. If not, are there any other candidates out there? -- Pob hwyl / Best wishes Kevin Donnelly www.kyfieithu.co.uk - KDE yn Gymraeg www.eurfa.org.uk - Geiriadur rhydd i'r Gymraeg www.rhedadur.org.uk - Rhedeg berfau Cymraeg www.cymrux.org.uk - Linux Cymraeg ar un CD -- Check the headers for your unsubscription address For additional commands send e-mail to suse-linux-e-help@suse.com Also check the archives at http://lists.suse.com Please read the FAQs: suse-linux-e-faq@suse.com
