Gnuplot Installation Under Windows, Linux and MacOS - Solution

Judging by the number of people asking on the forums, this a very common FAQ.

Windows

Download and install Gnuplot from http://www.gnuplot.info/download.html.

Ensure that the Gnuplot binary folder is registered in the PATH environment variable so that you can call the Gnuplot executable from any folder.

MacOS

You may find that Gnuplot reports that the wxt is an unknown terminal type; in which case, use the following command :

Uninstall your current version of Gnuplot and then install the +wxt variant.

port variants gnuplot to list available variants.

sudo port install gnuplot +wxwidgets

Note, after this I had to reboot MacOS to enable Gnuplot to recognize the new terminal types.

Linux

Under Linux you need to install both Gnuplot and Gnuplot-X11 :

sudo apt-get install gnuplot

sudo apt-get install gnuplot-x11

If you wish to interface to Gnuplot from a C/C++ application then the Gnuplot/C wrapper could be the answer to your search : https://sourceforge.net/projects/gnuplotc/.
