You can plot functions:
gnuplot> plot [x=0:100] 5*x*x*x+10
If you have x,y data in a file, like
1 10 5 10.4 20 15 100 17 354 20 1000 30
then you can plot the data:
gnuplot> plot "filename"
You can choose to have log/log plots. This command sets both x and y axes to log10:
gnuplot> set logscale xy 10 gnuplot> plot [.01:1000] [.01:1000] "filename"
Warning:If you will be measuring things on these graphs, make sure that the horizontal and vertical axes have the same scale. You may have to use the mouse to resize the plot window.
