User to the excellent documentation which accompanies gnuplot. We want to plot more than one function that’s why we have to divide the two. As you can see, the definitions of functions in gnuplot are straight forward. See the various plot predicates for further example usage.įor a complete description of the avilable options we refer the Gnuplot isnt particularly good at guessing good initial values for these parameters, so we should set them by hand to some approximate values before asking Gnuplot to adjust them. Therefore we specify our functions and plot them: a 0.9 f(x) a sin(x) g(x) a cos(x) Plot plot f(x) title 'sin (x)' with lines linestyle 1, \ g(x) notitle with lines linestyle 2. Gnuplot.exe or wgnuplot.exe, you must have the
