asciichart is a funny JavaScript chart library which helps you render a chart of plotted data using ASCII Art text.

Installation:

How to use it:

Download and import the asciichart into the html page.

Define your own data series in the JavaScript:

var s0 = ...

Plot the data into the chart:

asciichart.plot (s0);

Possible configuration options which can be passed as the second parameter to the asciichart.plot function:

asciichart.plot (s0,{
  // axis offset from the left (min 2)
  offset:  3,          
  // padding string for label formatting (can be overrided)
  padding: '',  
  // any height you want
  height:  10,
  
  // the label format function applies default padding
  format:  function (x, i) { return (padding + x.toFixed (2)).slice (-padding.length) }
});
