Version 6.15 of RGraph is now available

Written by Richard Heyes, RGraph author, on 23rd December 2023

The latest version of RGraph - version 6.15 - is now available to download from the download page. Here's what's new in this release:

  • From this version the Activity meter is able to accept the property names in any letter-case you choose - not just what is listed on the documentation page. This is a test and if there are no problems reported it will be rolled out to all of the chart types so that letter-case will no longer be an issue when you're configuring your chart - you'll be able to use any letter-case that you prefer (eg marginLeft, MarginLeft, marginleft, MARGINLEFT or even MaRgInLeFt).
  • The svg Bar chart is now adjustable. By extension this means that the svg VProgress bar can be made adjustable too.
  • You can now have rounded corners on the canvas Gantt chart.
  • RGraph now has a YouTube channel There's not a great deal of content on there at the moment - more videos will be coming!
  • The Horizontal Progress bar and the Vertical Progress bar can now be made to be rounded by using the corners and cornersRoundRadius properties.
  • Added support to both the canvas and svg Horizontal Bar chart for filled Vertical Line charts.
  • The sample code blocks on the RGraph website now have a copy link at the top right corner which copies the contents of the code block to the clipboard. The demo pages in the download archive also have this link on them. Also, the demo pages now create the pre sections dynamically based on the source code on the page. This makes the demo pages smaller and more maintainable.

You can read the full list of changes on the changelog page and you get hold of RGraph on the download page.
