There are four functional Gnuplot installations:
module load chpc/compmech/gnuplot/5.2.7-qt
If you do not want the qt output, set the appropriate terminal type.
All of these are available as modules, please use
module avail 2>&1 grep gnuplot. Please refer to the Gnuplot web site for instructions on using gnuplot. For interactive graphics, a graphics-enabled environment will be required, therefore refer to the page on Remote Visualization for instructions on setting up a connection to the visualization node. Gnuplot has been around for 30 years, but is still very useful. The “dumb” terminal mode can be used to generate funky 1970's style ASCII graphics - a feature that can be surprisingly handy when checking convergence of cluster runs over a low-bandwidth connection.
