freqchart(1) -- Frequency Chart
===============================
Command line tool for generating frequency charts
Installation
------------
[sudo] npm install -g freqchart
Basic Examples
--------------
`freqchart` will read from stdin by default a file in the format of `count key\ncount key\n...`.
$ cat data.txt
5 dave
7 mike
9 skye
13 shaggy
$ cat data.txt | freqchart
4 unique keys
34 total count
shaggy |-------------------------------------- | 13 (38.2%)
skye |-------------------------- | 9 (26.5%)
mike |--------------------- | 7 (20.6%)
dave |--------------- | 5 (14.7%)

Subsequently, this will work if fed the data of a Git Repository with `git shortlog -ns`.
`freqchart` will also take filenames to read from as additional arguments.
You can supply a file with `-r` that contains keys (names in this case) to remove from the final
output.
$ cat remove.txt
mike
$ freqchart -r remove.txt data.txt
4 unique keys
34 total count
shaggy |-------------------------------------- | 13 (38.2%)
skye |-------------------------- | 9 (26.5%)
dave |--------------- | 5 (14.7%)
0 crossed out
1 removed

You can supply a file with `-x` that contains keys (names in this case as well) to cross out of the output
(and color red).
$ cat crossout.txt
shaggy
$ freqchart -x crossout.txt data.txt
4 unique keys
34 total count
X shaggy |-------------------------------------- | 13 (38.2%)
skye |-------------------------- | 9 (26.5%)

Advanced Examples
-----------------
Simulate flipping a coin (with bash and pipelines)
$ for ((i=0;i<100;i++)); do ((RANDOM % 2 == 1)) && echo 'heads' || echo 'tails'; done | sort | uniq -c
59 heads
41 tails
$ for ((i=0;i<100;i++)); do ((RANDOM % 2 == 1)) && echo 'heads' || echo 'tails'; done | sort | uniq -c | freqchart
2 unique keys
100 total count
tails |------------------------------------------------------- | 55 (55.0%)
heads |--------------------------------------------- | 45 (45.0%)
