Version 5.26 of RGraph is now available

Written by Richard Heyes, RGraph author, on 3rd October 2020

It's been only five weeks this time since version 5.25 and here's a new version: 5.26. There's nothing particularly ground-breaking in this release and you can see exactly what is in this release by looking through the changelog.

Changes and additions include:

  • Added a few new labelsAbove properties to the Gauge chart.
  • The svg charts that use axes can now show x-axis and y-axis titles.
  • The canvas 3D charts (that use bars) have had their tooltip positioning tweaked.
  • The Google Sheets code has had a long-standing bug resolved (where multiple blocks were used on the page).
  • The internal prop.xxx property that referred to the properties has been changed to properties.xxx. This improves readability and makes the code easier to follow.

There are a few other things that you can read about on the changelog but these are the main things.
