Background I keep coming back to Gnuplot. It’s been 15 years, and I still come back to it for my plotting needs often and it has never disappointed. I used it extensively for my PhD research: monthly reports, quick updates on some new findings, academic papers, my thesis, and my final presentation. Throughout the years, I have used it for other things as well. A few years ago at work, I hooked it up to some output from a legacy system, and using the native terminal support, created a quick poor man’s dashboard.
