"description": "# asciichart\n\n[](https://npmjs.com/package/asciichart) [](https://travis-ci.org/kroitor/asciichart) [](https://coveralls.io/github/kroitor/asciichart?branch=master) []()\n\nConsole ASCII line charts in pure Javascript (for NodeJS and browsers) with no dependencies. This code is absolutely free for any usage, you just do whatever the fuck you want.\n\n![\"Console](\"https://cloud.githubusercontent.com/assets/1294454/22818709/9f14e1c2-ef7f-11e6-978f-34b5b595fb63.png\")
\n\n## Usage\n\n### NodeJS\n\n```sh\nnpm install asciichart\n```\n\n```javascript\nvar asciichart = require ('asciichart')\nvar s0 = new Array (120)\nfor (var i = 0; i < s0.length; i++)\n s0[i] = 15 * Math.sin (i * ((Math.PI * 4) / s0.length))\nconsole.log (asciichart.plot (s0))\n```\n\n### Browsers\n\n```html\n\n\n \n \n \n asciichart\n \n \n \n \n \n\n```\n\n### Options\n\nThe width of the chart will always equal the length of data series. The height and range are determined automatically.\n\n```javascript\nvar s0 = new Array (120)\nfor (var i = 0; i < s0.length; i++)\n s0[i] = 15 * Math.sin (i * ((Math.PI * 4) / s0.length))\nconsole.log (asciichart.plot (s0))\n```\n\n![\"Console](\"https://cloud.githubusercontent.com/assets/1294454/22818807/313cd636-ef80-11e6-9d1a-7a90abdb38c8.png\")
\n\nThe output can be configured by passing a second parameter to the `plot (series, config)` function. The following options are supported:\n```javascript\nvar config = {\n\n offset: 3, // axis offset from the left (min 2)\n padding: ' ', // padding string for label formatting (can be overrided)\n height: 10, // any height you want\n\n // the label format function applies default padding\n format: function (x, i) { return (padding + x.toFixed (2)).slice (-padding.length) }\n}\n```\n\n### Scale To Desired Height\n\n![\"Console](\"https://cloud.githubusercontent.com/assets/1294454/22818711/9f166128-ef7f-11e6-9748-b23b151974ed.png\")
\n\n```javascript\nvar s = []\nfor (var i = 0; i < 120; i++)\n s[i] = 15 * Math.cos (i * ((Math.PI * 8) / 120)) // values range from -15 to +15\nconsole.log (asciichart.plot (s, { height: 6 })) // this rescales the graph to \u00b13 lines\n```\n\n![\"Console](\"https://cloud.githubusercontent.com/assets/1294454/22825525/dd295294-ef9e-11e6-93d1-0beb80b93133.png\")
\n\n\n### Auto-range\n\n```javascript\nvar s2 = new Array (120)\ns2[0] = Math.round (Math.random () * 15)\nfor (i = 1; i < s2.length; i++)\n s2[i] = s2[i - 1] + Math.round (Math.random () * (Math.random () > 0.5 ? 2 : -2))\nconsole.log (asciichart.plot (s2))\n```\n\n![\"Console](\"https://cloud.githubusercontent.com/assets/1294454/22818710/9f157a74-ef7f-11e6-893a-f7494b5abef1.png\")
\n\n### See Also\n\nA util by [madnight](https://github.com/madnight) for drawing Bitcoin/Ether/altcoin charts in command-line console: [bitcoin-chart-cli](https://github.com/madnight/bitcoin-chart-cli).\n\n\n\n### Ports\n\nSpecial thx to all who helped port it to other languages, great stuff!\n\n- [Python port](https://pypi.org/project/asciichartpy) included!\n- Java: [ASCIIGraph](https://github.com/MitchTalmadge/ASCIIGraph),\u00a0ported by [MitchTalmadge](https://github.com/MitchTalmadge). If you're a Java-person, check it out!\n- Go: [asciigraph](https://github.com/guptarohit/asciigraph), ported by [guptarohit](https://github.com/guptarohit), Go people! )\n- Haskell: [asciichart](https://github.com/madnight/asciichart), ported by [madnight](https://github.com/madnight) to Haskell world!\n- Ruby: [ascii_chart](https://github.com/zhustec/ascii_chart), ported by [zhustec](https://github.com/zhustec)!\n- Elixir: [asciichart](https://github.com/sndnv/asciichart), ported by [sndv](https://github.com/sndnv)!\n- Perl: [App::AsciiChart](https://github.com/vti/app-asciichart), ported by [vti](https://github.com/vti)!\n- C: [plot](https://github.com/annacrombie/plot), ported by [annacrombie](https://github.com/annacrombie) with a ruby extension!\n\n### Future work (coming soon, hopefully)\n\n- multi-line colored charts in console!\n- levels and points on the graph!\n- even better value formatting and auto-scaling!\n\n\n\n\n\n",
