Text Graphs with GNUPlot!

I stumbled across this article a few weeks ago, and kept it open in my browser until I could come up with something (semi-) useful to do with it: Plotting data in the terminal with gnuplot…

I had done some work last year at ERLPhase to analyze some data, including doing FFTs, etc.  I played around and did a comparison between JPEG graphics and text graphs.  Check it out!

Click here to see the text FFT in alone in a page or new tab or new window, depending on your browser settings.

The secret to doing a text plot is in the two statements:

set terminal dumb 250 60
plot FftFileName using 2:5 with linespoints

Where the output is 250 characters wide x 60 lines high, and the input data is in the file FftFileName.

I don’t know why, but I find that just… fascinating…   wow!
