How to use Gnuplot to Graph Data on the Raspberry Pi #piday #raspeberrypi @Raspberry_Pi

NewImage

Raspberry Pi Spy posted this useful tutorial on using a Raspberry Pi to graph data.

I was recently testing a sensor which needed calibrating. This involved plotting some data and making some adjustments based on the resulting graph. As a Windows user this is a task I would normally perform in Microsoft Excel or LibreOffice Calc.

In this case I decided to try to do it on the Pi given I was already working wthin the LXDE environment. Could I do some simple plots without getting frustrated with tons of obscure command line syntax?

The answer was yes and came in the form of “gnuplot”, a command-line driven graphing utility. It’s got a lot of options but it only takes five minutes to master the basics.

This tutorial just scratches the surface but aims to provide a quick reference for creating graphs from simple datasets.

Check out the full tutorial here.
