An older demo has been added back into the RGraph download archive

About

RGraph is a JavaScript charts library based on HTML5 SVG and canvas. RGraph is mature (over 17 years old) and has a wealth of features making it an ideal choice to use for showing charts on your website.

Version 7.01 released

Version 7.01 (released in October 2025) is the latest version of RGraph and now includes a new tree structure object. The accompanying Treemenu object can then turn the object into a fully dynamic tree menu. You can read the API documentation for the tree on the main API documentation page and see an example of the Treemenu feature by following this link...

New HTML datagrid

In the April 2025 (v6.21) release a new datagrid object was added. This makes it easy to add static or dynamic data tables to your pages. It can be used whether you use the canvas or SVG libraries or entirely standalone.

RGraph can be used for free under the GPL or if that doesn't suit your situation there's an inexpensive (£129) commercial license available.

I realised recently that a demo that I showed a screenshot of on this blog, albeit some time ago, wasn't in the download archive. So I've remedied this and the new demo is called demos/bar-grouped-purple.html (it'll be in the next release). Here's an example of it in case you're curious. The source code of the chart is as follows:

<script>
    labels = [
        '0 to 4','5 to 9','10 to 14','15 to 19','20 to 24','25 to 29','30 to 34',
        '35 to 39','40 to 44','45 to 49','50 to 54','55 to 59','60 to 64',
        '65 to 69','70 to 74','75 to 79','80 to 84','85 to 89','90+'
    ];
    
    myData = [
        [750,650],[850,800],[900,850],[1500,2800],[4000,7000],
        [6300,11500],[7000,11200],[6800,9800],[6800,9500],
        [7500,11200],[8500,12300],[8500,11000],[7500,7800],
        [6050,4500],[6900,5000],[8000,6400],[9000,8900],
        [8000,10000],[5900,11850]
    ];

    new RGraph.Bar({
        id: 'cvs',
        data: myData,
        options: {
            title: 'A demo of the new style of tooltips',
            titleSize: 16,
            titleBold: true,
            tooltips: '%{global:labels[%{group}]} %{key}',
            tooltipsFormattedKeyColorsCss: {
                border: '1px solid #ccc'
            },
            tooltipsFormattedKeyLabels: ['Male','Female'],
            tooltipsCss:{
                textAlign: 'left'
            },
            tooltipsOffsety: -5,
            colors: ['#5C1955','#62A3B3'],
            marginBottom: 75,
            marginLeft: 75,
            xaxis: false,
            yaxis: false,
            xaxisLabels: labels,
            xaxisLabelsAngle: 45,
            xaxisLabelsOffsety: 5,
            yaxisScaleMax: 15000,
            backgroundGridVlines: false
        }
    }).draw();
</script>
