What is the best way to plot data from an url?
Currently, I have
pl "<wget -q -O - http://skuld.bmsc.washington.edu/scatter/data/Ta.dat" us 1:2
The option -q (quiet) suppresses download information and -O - redirects to stdout.
This relies on wget on Linux.
But I think, I have seen somewhere an even easier way.
