About

RGraph is a JavaScript charts library based on HTML5 SVG and canvas. RGraph is mature (over 18 years old) and has a wealth of features making it an ideal choice to use for showing charts on your website.

Version 7.10 released

Version 7.10 (released in January 2026) is the latest version of RGraph and contains various updates to the code which you can see on the changelog page. There's also a big tidy up in terms of comments and a significant change to the way that the internal code is referenced which should lead to a performance improvement in effects and animations.

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.

License

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.

Hi there,

There's no native PDF export functionality - you can only export to an image and that's documented here:

https://www.rgraph.net/install/integration.html#image

You could then use that image (you would probably want to clear the canvas to a white background color first otherwise you'll probably end up with a black background) when generating your PDF. But no native PDF export I'm afraid.

To clear the canvas to a white color you can either use the backgroundColor property if it's available or you can clear the canvas using an API function like this:

new RGraph.Rose({
    id: 'cvs',
    data: [1,2,3,4,5,6,7,8,9],
    options: {
    }
}).on('beforedraw', function (obj)
{
    RGraph.clear(obj.canvas, 'white');
}).draw();
