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

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
