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.

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!
