New datagrid in v6.21
In version 6.21 a new datagrid object has been 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 22nd January 2022RGraph version 6.06 is now available! In the first release of 2022 the main change is that there's now a set of functions that are dedicated to making importing data from the query string (the URL) easier. These new functions are called:
RGraph.GET.numberRGraph.GET.stringRGraph.GET.jsonRGraph.GET.array
SVG:
RGraph.SVG.GET.numberRGraph.SVG.GET.stringRGraph.SVG.GET.jsonRGraph.SVG.GET.array
RGraph.GET.json function is most useful
in my opinion as it allows you to import an entire
javascript object which can contain multiple things - for
example both data and labels. You should be aware, though,
that if not properly encoded json can interfere with seo
efforts.
You can read more about the query string functions on this page.
There are a few other changes that you can read about
in
the release notes.
