Version 6.06 of RGraph is now available

Written by Richard Heyes, RGraph author, on 22nd January 2022

RGraph 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.number
  • RGraph.GET.string
  • RGraph.GET.json
  • RGraph.GET.array
And for SVG:
  • RGraph.SVG.GET.number
  • RGraph.SVG.GET.string
  • RGraph.SVG.GET.json
  • RGraph.SVG.GET.array
The 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.

You can download the software from the download page:
