Quickly graph a list of numbers

gnuplot -persist <(echo "plot '<(sort -n listOfNumbers.txt)' with lines")
Useful when you've produced a large file of numbers, and want to quickly see the distribution. The value of y halfway along the x axis is the median. Simple! Just create the listOfNumbers.txt file with a number on each line to try it out.

I think you could combine this with graphviz for some pretty awesome and simple automated vizualization tools.

Or when used in a pipe whatever | gnuplot -persist <(echo "plot '<(sort -n)' with lines") Or without "sort" whatever | gnuplot -persist <(echo "plot '<(cat -)' with lines") Newer versions of Gnuplot may understand "plot '-'", but my 4.2.6 doesn't. whatever | gnuplot -persist <(echo "plot '-' with lines")
