Installation

This page guides you through installing fplot and its required dependencies.

1. Install gnuplot

fplot is a high-level interface for gnuplot, so you must have gnuplot installed on your system.

macOS

Using Homebrew:

brew install gnuplot

Debian / Ubuntu

sudo apt-get update
sudo apt-get install gnuplot

Arch Linux (&MSYS2)

sudo pacman -S gnuplot

Windows

You can download a gnuplot installer from the official gnuplot website. After installation, ensure that the gnuplot executable is in your system's PATH.

To verify the installation, open a terminal and run:

gnuplot --version

You should see the installed version of gnuplot.

2. Install fplot

You can use LuaRocks,(the package manager for Lua modules), to install fplot, or you can git clone the github repository.

luarocks install fplot

3. Verify the Installation

You can verify that fplot is installed correctly by running the following code.

Fennel

Create a file test.fnl:

(local fplot (require :fplot))
(print "fplot loaded successfully!")

(fplot.plot
  {:options {:title "Test Plot"}
   :datasets [{:data [1 2 3 4]}]})

Run it from your terminal:

fennel test.fnl

A plot window should appear with a simple line graph.

Lua

Create a file test.lua:

local fennel = require("fennel") fennel.install()
local fplot = require("fplot")
print("fplot loaded successfully!")

fplot.plot({
  options = { title = "Test Plot" },
  datasets = {
    { data = {1, 2, 3, 4} }
  }
})

Run it from your terminal:

lua test.lua

A plot window should appear, just like the Fennel example.

If the plot window appears, you have successfully installed and configured fplot!
