Overview

cl-plot is a thin Common Lisp Wrapper for gnuplot It expects gnuplot at /usr/bin/gnuplot (change to your needs using the variable *GNUPLOT-COMMAND*).

The central function is plot, which at this point accepts lists, one-dimensional arrays or functions. plot is implemented as a generic function so that it can be specialized on different data types and easily extended (see for example the incudine-plot package on this github account which is used for visualising musical data like envelopes or buffers).

The plot function returns its argument unchanged. This enables to wrap the (plot …) form around suitable subexpressions within code to graphically monitor intermediate results of larger code blocks without changing the overall outcome of the code.

INSTALLATION

cl-plot depends on uiop.

The recommended way is to use quicklisp and put the cl-plot folder into <user-home-dir>/quicklisp/local-projects/.

Then load it with

CL-USER> (ql:quickload "cl-plot")
To load "cl-plot":
Load 1 ASDF system:
cl-plot
; Loading "cl-plot"
.
("cl-plot")
CL-USER> (in-package :cl-plot)
#<PACKAGE "CL-PLOT">
CL-PLOT> 

Plotting Data Lists

;;; 2-dimensional:

(plot
 (loop for count below 20
    collect (list count (random 40.0)))
 :grid nil)

;;; 1-dimensional:

(plot
 (loop for count below 20
    collect (random 40.0)))

Plotting Arrays

(plot #(3 1 8 6 5 2 4))

(plot #((0 3) (1 1) (2 8) (3 6) (4 5) (5 2) (6 4)))

(plot #(#(0 3) #(1 1) #(2 8) #(3 6) #(4 5) #(5 2) #(6 4)))

Plotting Functions

(plot #'sin :region `(0 ,(* 2 pi)))

(plot #'exp :region `(0 4))

;; default region is '(0 1)

(plot #'sin)
