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 18th June 2025
Here's an update for about what's currently happening with RGraph at the moment. A new release is nearing finalisation and it has some interesting updates in it to the datagrid such as searching (both basic and regular expression) and paging (client and server based), minor updates to the ModalDialog that allow you to rotate the dialog when showing or hiding it, a couple of new datetime functions that mimic PHP functions and make handling dates and times far easier, layout updates to the various API documentation pages, the ability to add your event listener functions inline within the configuration instead of using the on() function and then there's my favourite. This I might hold back for version 6.23 - but text appearance on canvas has never been very good in my opinion. Certainly not as good as SVG. But now I've happened across a technique that makes the text appearance much better. Here's an example of a regular Bar chart that hasn't been tweaked followed by a version of the same chart but having been tweaked to improve the text appearance:
And here's a close-up of the "Gazza" label in the original (current) way that RGraph renders text and the new style:
Certainly an improvement I think that you'll agree! It still needs more work - especially in terms of working out coordinates for dynamic features. But the much improved appearance makes this a feature worth holding your breath for (but not too long - you do need to keep breathing!).
