Gnuplot
Run Gnuplot Interactively on the Cluster¶
Overview¶
- Gnuplot is a portable command-line driven graphing utility designed to allow scientists and student to visualize mathematical functions and data interactively.
- This guide will cover how to use Gnuplot interactively on the cluster.
- More information about Gnuplot can be found on their homepage
Note
The following recaps assume that you have already set up VNC or X11 before.
Recap of Connecting to VNC¶
- Please see the VNC guide for instructions on how to set up the Interactive VNC session
Recap of Connecting to X11¶
- Start up your X Server (XQuartz on macOS, VcXsrv on Windows).
- SSH in with the -Y flag like this:
ssh -Y someuser3@login-s.pace.gatech.edu
.
Starting Gnuplot in VNC¶
- Open terminal in VNC window by clicking top left
Applications
>System Tools
> scroll down toterminal
. - All commands here on will be typed in terminal in VNC.
- Run
module load pgi/12.3
- Run

Gnuplot Example¶
- Following one of the examples found here we can see this in the Gnuplot window after entering
plot sin(x) title 'Sine Function', tan(x) title 'Tangent'
in the Gnuplot prompt:
