"In my many years of working with data, I have used pretty much every similar charting software out there, but none come anywhere near as close. I have built literally hundreds of documents using RGraph and would never even consider changing from what is one of the best pieces of software I have ever used. I like it so much, I link to it from our homepage - and everyone that uses RGraph should do too!" - James Welch, CTO Online Ventures

Lots of charts, features and documentation

There are lots of plus points to using RGraph to make your charts with, and it can make many different chart types, which you can see from the RGraph documentation and the examples. To see all of the examples (there are over 350!) you can take a look at the demo area.

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>

    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 .
