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 7.11
Version 7.11 (released in March 2026) is the
latest version of RGraph and contains just a few
updates to the code which you can see on
the changelog page. There's
a new dumbbell variation for the Bar and Horizontal bar
charts (both SVG and canvas) and the
front page layout of the
website has been tweaked.
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.The new RGraph Tree structure object
Written by Richard Heyes, RGraph author, on 20th September 2025
Now all the cheering and celebrations have died down from the release of version 7.00 (...) I've started working on adding a new Tree structure object to RGraph that will be a part of version 7.01. This will make creating and manipulating tree structures easier.
Something that I've added to this tree structure that may make it very interesting to you is the ability to show a folder tree. This is something that I first did over 20 years ago (!) when I was writing PHP code for the PEAR project (HTML_TreeMenu if you're interested).
so you might think that it would a breeze for me. Well... in some respects! None of the code has come from the old project though - it's all brand new and up-to-date.
It could be very useful for menu systems - particularly for backends. It will be customisable of course and with data: sources for the images they won't rely on external files this time. If all goes to plan, the branches will be dynamically collapsible too like the old PEAR version was.
Oh, and as you can see from the image of music bands above - I had some pretty poor taste in music when I was younger!
