How to plot at terminal using GNUPlot

Gnuplot is an awesome graph plotting program that has been around since the time of dot-matrix printers and teletype terminals. Little wonder that it has support for such archaic output devices even today. One such output terminal supported by Gnuplot is called the dumb terminal.

I find the dumb terminal pretty useful to have around in the initial stages of plotting to get a rough idea of the data. The default terminal on Windows is called wxt and gnuplot pops up a new window to display the plot. If you find that and switching between windows distracting, use the dumb terminal which plots a quaint ASCII-art graph! 🙂

To switch to a dumb terminal:

gnuplot> set terminal dumb
