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.
Download
Get the latest version of RGraph (version 7.11, 21st March 2026) from

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.AJAX image uploads now available for forum posts
Written by Richard Heyes, RGraph author, on 6th May 2022
It seems to be quite the rage at the moment - ajax file
uploads for forms. So now you can attach up to three
images (each of which can be up to 100k in size) to your
forum posts (not replies though). If it gets abused I'll
have to review it's use - but I think it should be fine.
Famous last words...
I've also implemented deep anchors - so instead of just
linking to the page and then having to find the reply
that may interest you - you can link directly to it.
