The main that caught my eye was the plot on the right, which shows a few overlaid sinusoids, with the code used to generate them as the key. Here’s the code:
plot for [n=2:10] sin(x*n)/n with filledcurves
That’s right, one line for 8 plots! Version 4.3 of gnuplot introduces the
for keyword, which lets you sweep through numerical parameters and loop through strings. The help (see
help iteration with 4.3) has a few examples, which I’ve copied in below:
plot for [filename in "A.dat B.dat C.dat"] filename using 1:2 with lines plot for [basename in "A B C"] basename.".dat" using 1:2 with lines set for [i = 1:10] style line i lc rgb "blue" unset for [tag = 100:200] label tag
I downloaded and compiled the sources and whipped up a quick example of my own (I couldn’t get aquaterm going though). You can see it below:
I’ve got preliminary support going in the Gnuplot TextMate bundle, but I’m still not 100% happy with it yet.
