TIP: draw plots directly in terminal! (with iTerm2)
Example: your data is already in CSV format in "z.plt", this one-line command will render a plot and show it in the terminal:gnuplot -e 'set terminal png ; set output "plot.png"; plot "z.plt" using 0:7 with lines' && imgcat plot.pngThis is great for testing web site performance. The previous one line ran Apache Bench to beat the crap out of my local server, and write the output into a Gnuplot-compatible CSV file:ab -n10000 -c100 -g z.plt http://192.168.64.3:30260/
