What is RGraph? It's a web charts library that produces the charts dynamically with JavaScript. It can generate lots of different kinds of visualisations.
  • Easy to use
  • 50-60 different types of visualisation
  • Great device support
  • Excellent performance
  • Extensive documentation, examples and learning resources
  • Great support

RGraph is a quick and attractive charts library that's both easy to use and feature packed. Built on the widely supported canvas element desktop and mobile support is excellent and that allows you to create charts and dashboards that you can use on a wide range of devices. Owing to the fast rendering of canvas, your charts can be up to 10x faster than Flash or SVG based libraries. This means you can create good looking and informative charts and dashboards.

Versatile and customisable

The charts can be customised using the properties to look attractive and they can fit into your website easily. The charts are customised using simple JSON such as the code below.

<canvas id="cvs" width="650" height="250">[No canvas support]</canvas>

    window.onload = (function ()
        var bar = new RGraph.Bar({
            id: 'cvs',
            data: [
                [4,8,3],[5,2,1], [8,4,2],[3,6,1],[5,1,0],[2,5,1],[1,2,2]
            options: {
                variant: '3d', 
                strokestyle: 'rgba(0,0,0,0)',
                colors: ['Gradient(#fbb:red)', 'Gradient(#bfb:green)','Gradient(#bbf:blue)'],
                gutterBottom: 80,
                labels: ['Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday'],
                shadowOffsetx: 3,
                backgroundGridColor: '#eee',
                variantThreedAngle: 0.1,
                axisColor: '#ccc'

As well as customising the charts to look how you want you can manipulate the data to show different kinds of things - such as the fan style Line chart showing deviation from a predicted set of values .
