catchart

(pronounced ca-chart)

Pipe something from command line to a chart in the browser

uses chart.js for, ahem, charting...

command line

npm i -g catchart

catchart --help

simple y over t

echo 1\n2\n3\n | catchart

custom label / value

echo sunday,1,2,3\nmonday,4,5,6\ntuesday,7,8,9\n | catchart --labelSource=row

multiple data sets over time

echo 1,2,3\n4,5,6\n-1,-2,-3\n | catchart

other chart types, custom title

echo 1,2,3\n4,5,6\n-1,-2,-3 | catchart --title=catchart --chartType=bar

chart types: line, bar, radar, pie

JSON input works too!

echo "{ \"data\": 1 }"\n"{ \"data\": 2, \"label\": \"foo\" }"\n | catchart

api

catchart cli in it's simplest form, looks very much like this:

const catchart = require('catchart')
const Slicer = require('stream-slicer')

process.stdin.pipe(new Slicer()).pipe(catchart())

dev

• clone this repo
• hack
• gulp build; node emitter <csv | singlecsv | json> | node catchart`
• send a PR :)

TODOS

• refactor code, especially server
• write tests (right now using emitter.js to test manually)
