Version 6.05 of RGraph is now available

Written by Richard Heyes, RGraph author, on 14th November 2021

RGraph version 6.05 is now available! In this release, both the SVG and canvas versions of the Semi-circular Progress meter have had some attention and they now both support multiple values and scales. The canvas Line chart angled labels howto document has now been added as a core feature (ie it's now built into the Line chart) so it's much easier to implement on your own charts.
