conplot - console plotter via ascii art
Brendan O'Connor - brenocon@gmail.com - http://github.com/brendano/conplot
conplot is a script for when you have a file or stream of lots of numbers and
want to look at it fast. Needs many more features, but basics work.
Usage: pipe a column of numbers on stdin to conplot.rb. Tries to be smart
about other junk in the file. It is intended to work with shell tools like
perl -pe, awk/sed, wc, du, sort|uniq -c and the like.
Example: time.log is a big list of numbers from a (while sleep 1; do du -m db;
done) loop. I want to know how fast the db is growing over time.
$ wc -l time.log
77879 time.log
$ head -2 time.log
35 db
36 db
$ tail -2 time.log
14540 db
14540 db
$ cat time.log | conplot
14601

Features to do, that probably will never get done
* scatterplots!!! x,y as two columns on stdin. almost already supported.
* size according to terminal size (e.g. look at stty -a)
* histograms should be integrated as an option -- or, use github.com/stevej/conhist
