Line 2: Sets the number of samples to 5000.Line 1: Sets the x axis range from 0 to 350.Redo it as follows: gnuplot> set xrange įigure 1: Plot of the function y=cos(x)*x**3 Though correct, the graph doesn’t seem to reveal the exact nature of the function. At the GNUPlot prompt, type the following: gnuplot> plot cos(x)*(x**3) GNUPlot will auto-scale the axes to include all the data, and take ‘x’ as a variable. You will immediately see the sine plot popping up in a separate window. Type in the following at the gnuplot> prompt, and press Enter: gnuplot> plot sin(x) We all know what a sine function looks like.
