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 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...
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.
Get the latest version of RGraph (version 7.01, 8th October 2025) from
the download page. You can read the changelog here. There's also older versions available,
minified files and links to cdnjs.com hosted libraries.
Read the miscellaneous information
Various bits of information that don't fit elsewhere. This page is well

Margin sizing tool
Try the margin sizing tool
A simple margin sizing tool that may help you with the size of your
chart's margins. Simply drag the gray part of the tool around (which
represents the main part of your chart) and the sizes are updated
for you automatically.

documentation is a good place to start. It's quite extensive (there's
a lot there) so you may find that simply delving into it and getting the
information that you want may be a good way of getting through this page.
