Gnuplot> List of operators and functions gnuplot knows about You can execute some shell commands (like ls), using the ! operator first. Say, for instance, you forgot the name of the data file you wanted to plot, etc.) Sometimes you may find yourself wishing you could run a shell command while inside gnuplot. Executing Basic Shell Commands in GNUPLOT This is done merely by isolating them from other items with commas.Įtc. It is also possible to define functions and parameters on the `plot` command In part earlier in the stream of `gnuplot` commands (see `user-defined`). The expressions may be defined completely or A function is a mathematical expression or a pair of mathematicalĮxpressions in parametric mode. Where either a or the name of a data file enclosed in quotes is Furthermore, `plot`'s `axes` option does not exist for `splot`. Work for both `plot` and `splot`, there are small differences between these

Note specifically that although the `binary ` variation does `plot` and `splot` contain many common features see `splot` for differences. `plot` is used to draw 2-dįunctions and data `splot` draws 2-d projections of 3-d surfaces and data. Plots of functions and data in many, many ways. `plot` is the primary command for drawing plots with `gnuplot`. If it is available, you should see something like You can run gnuplot straight from a terminal (command-line) using the command gnuplot. fonts folder in my home directory with all of my fonts in it, so I would setĮxport GDFONTPATH=$HOME/.fonts Running GNUPLOT and Getting Help Using Cygwin on the PC, a typical choice isĮxport GDFONTPATH=/cygdrive/c/Windows/Fonts If you want to expand the fonts that gnuplot knows about when printing image files (like GIF, PNG, JPG, etc.), you need to set the GDFONTPATH environment variable to point to directories that contain font files.

It's free! Though not actually associated with the GNU project or the FSF (Free Software Foundation).

It's widely used, so there are many, many tutorials and references around for gnuplot (including this one).The learning curve isn't nearly as steep as you'd think with it being a command-line-only interface.Once you become comfortable with gnuplot, it is fast and easy to create customizable plots (especially once you've built up an army of scripts).It is incredibly flexible, giving you control over almost every aspect of your graph.It can print to an almost limitless number of file formats (terminals), so the terminal you want is almost certainly available.It has an expansive built-in help function to help you every step of the way.You only have to spend the time formatting a single graph, and all other similar ones can be created instantly (and identically) from that template It is scriptable - that is, you can spend a little bit of time getting your graph to look just the way you want it, then you have a script that will work for whatever data sets you have.You may ask, why pick gnuplot over some of the other plotting alternatives like Excel (or some other spreadsheet), origin, matplotlib, etc.? I'll try to list some of the reasons I can think of, starting with the most important:
