Version 6.17 of RGraph is now available

Written by Richard Heyes, RGraph author, on 10th March 2024

The latest version of RGraph - version 6.17 - is now available to download from the download page. Here's what's new in this release. There's one very notable change in this release and that's the introduction of the clip property. This property allows you to easily restrict what actually gets drawn on to the canvas or svg which opens up some very interesting possibilities. This property has been added to both the canvas and svg charts.

  • Added the Funnel chart grow effect.
  • A new option - clip - has been added to all of the svg and canvas charts. This allows you to (much) more easily generate multi-color charts like demos/svg-line-clipped.html or demos/svg-line-clipped2.html (which you can find in the download archive). This new option has been added to all of the available chart types. You can read more information about it on the clipping documentation page. This information applies to both the svg and canvas charts.
  • The svg Line chart property tooltipsHotspotSize has been added which controls the size of the hotspots that trigger the tooltips. It defaults to 5.
  • Added the svg Waterfall chart grow effect.

An interesting demo that uses the new clip property to good effect is the demos/svg-line4-clipping.html file. This demo allows you to easily compare two datasets by showing and hiding Line charts as you move your mouse left and right over them. This demo is in the download archive.

You can get hold of RGraph on the download page.
