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 on CodePen because the code for it will be a part of version 6.09 and that hasn't been released yet. Soon though...!

It acts just like the Bar chart wave effect and looks particularly good when it's part of a transition effect - and there'll be an example of that on the Line chart documentation page and also in the download archive (from version 6.09).
