Quick plotting of a function

The arguments of "seq" indicate the starting value, step size, and the end value of the x-range. "awk" outputs (x, f(x)) pairs and pipes them to "graph", which is part of the "plotutils" package.

There are 8 alternatives - vote for the best!

What others think

very sweet. not much daily use for me tho.

using 'gnuplot' would be much easier.

echo 'plot cos(0.5*x)*sin(5*x)' | gnuplot -persist

Comment by jxy 321 weeks and 2 days ago

Gnuplot is an alternative, yes, but not necessarily easier. By changing the seq arguments, you can change the x range and step size. Your example with Gnuplot doesn't do this unless you bloat the command with 'set xrange ...' etc.

Of course, for finer tuning and better, one can create a gnuplot script. But this site is about one-line commands, and this command is meant only for a quick look at a function.
