New Line chart wave effect

Written by Richard Heyes, RGraph author, on 17th August 2022


I think that I may have mentioned this on the RGraph socials - but not here. So here's a mention of the new Line chart wave effect. It's was initially on CodePen because the code hadn't been released - but now it has so here it is!

It acts similarly to the Bar chart wave effect and looks particularly good when it's part of a transition effect and you can see that above and also in the download archive (from version 6.09).
