Need to plot some data from Common Lisp? This will solve your problem by making a pretty plot in your web browser, effectively using that browser as a display for your chart. It uses a cute Javascript plotting widget known as flot. But it can do much more; you can push arbitrary content to a webpage, and by using other Javascript widgets lots of other things are possible; including maps, rich text editors, syntax highlighting, etc. etc.
First: clone this repository (to ~/.quicklisp/local-projects for example),
then having assured that ASDF can find it (say by resetting ASDF's source respository
(asdf:clear-source-registry)), and then load and run the application as so:
> (ql:quickload "plot-window")
> (cl-user:initialize-application)Second: Visit http://localhost:8765/ in a quality web browser. I've only tried chrome. The resulting page becomes your REPL's display window.
Third: Load up an example, in this case a plot widget: (ql:quickload "plot-window-flot")
> (pw:plot (loop for i below 50 collect (list i (random 20))))You can clear the window with (ps:clear-display-window), and you can add single elements to the page using (ps:add-element "<p>Hi there</p>")
A number of examples are in the example's subdirectory. Each of these has it's on asd. You may load them all via (ql:quickload "plot-window-examples"). And once they are all loaded you can run a little demo: (ql:demo t)
The chart is drawn by flot, a javascript library. The page is rendered via Hunchentoot. The dynamic updating is done via websockets (with the help of clws). A tangle of javascript glues it all together, and that's implemented using parenscript. Various standard libraries on the javascript and common lisp side are used: Hunchentoot, Parenscript, jQuery, etc.
