What do you expect it to show? Do you treat Char as a number? or are you interested in the number of times each character occurs in your vector? In the later case you may be looking for a barplot instead of a histogram

[Good luck with reading that minified code… it’s still “free software”; just wouldn’t be “GPL-compatible”… In general that would mean not ok to distribute with GPL… (LGPL would be ok) but “arms-length” probably applies here, and js runs in the browser (another process) so I’m pretty sure you’re ok (at least if your GPL would be in non-browser).]
I didn’t check further (other dependencies), it seems everything running on your machine is free. I’m not sure SaaS applies, if so you might have other concerns with that (see Stallman on that too…)…
Not sure what you’re paying for (optionally) - didn’t check - probably just some optional convenience features.
I too a look at the page (assume PR is in); and Vincent’s code:
Neither works; I’m on Ubuntu 16.04, of course with Python [2.7.12] installed. Strange that PyPlot didn’t work to begin with, and (to me), I guess I was asking for Python install here, but not two versions… older python-2.7.11-0 and newer python-2.7.13 (and [more than one?] [mini]conda… and PyPlot still failes after…:

[PS. Is it only me, is Discourse slow? Annoyingly, order of letters that I type in, keep appearing in the incorrect order… I guess it’s a general [here: Brave beta w/“load average: 0,11”] browser issue (Chrome derivative; if I recall happened before with it and/or Firefox; what’s the best browser…?)… Happens on other websites, such as Quora (but not in the REPL).]
meaning new in GPLv3, and its absense in GPLv2 (and other wording) meaning, considered there binary, ont ok as a source; not allowed to redistribute as such, without “corresponding source”, e.g. the non-minified version). See also e.g. LibreJS.]
