* clgplot
clgplot is a Gnuplot front-end on Common Lisp.
** Dependencies
Gnuplot (>4)
** Installation
#+BEGIN_SRC sh
cd ~/quicklisp/local-projects
git clone https://github.com/masatoi/clgplot.git
#+END_SRC
In case of using Roswell, simply
#+BEGIN_SRC sh
ros install masatoi/clgplot
#+END_SRC
#+BEGIN_SRC lisp
(ql:quickload :clgplot)
#+END_SRC
** Usage
clgplot generates a data file and a setting file of Gnuplot to tmp directory and execute Gnuplot with -persist option.
Paths to these files or command can be changed as below.
#+BEGIN_SRC lisp
(defparameter clgp:*gnuplot-path* "gnuplot")
(defparameter clgp:*tmp-dat-file* "/tmp/clgplot-tmp.dat")
(defparameter clgp:*tmp-gp-file* "/tmp/clgplot-tmp.gp")
#+END_SRC
*** Plot of single function
#+BEGIN_SRC lisp
(defparameter *x-list* (loop for i from (- pi) to pi by 0.1 collect i))
(clgp:plot (mapcar #’sin *x-list*))
#+END_SRC
[[./docs/img/clgp01.png]]
Plots can be output to a file as follows.
#+begin_src lisp
(clgp:plot (mapcar #’sin *x-list*) :output "/path/to/file.png")
(clgp:plot (mapcar #’sin *x-list*) :output "/path/to/file.png" :output-format :png)
(clgp:plot (mapcar #’sin *x-list*) :output "/path/to/file.pdf" :output-format :pdf)
(clgp:plot (mapcar #’sin *x-list*) :output "/path/to/file.eps" :output-format :eps)
#+end_src
*** Plot of multiple functions with annotations
#+BEGIN_SRC lisp
(clgp:plots (list (mapcar #’sin *x-list*)
(mapcar #’cos *x-list*)
(mapcar #’tan *x-list*))

:x-range (list (- pi) pi)
:y-range ’(-1 1)

Divide samples by the range width equally and count the number of samples appear in each bins.
Separate interval (a,b) equally to n bins, then return index of the bin which x belongs to.
