I want to show three series with 3D columns, series behind each other (z axis) so that the front columns are a stack of 2 series.

I can do stacked but columns are on x axis: [https://jsfiddle.net/yfohmagd/][1]
Or columns are on z axis but not stacked: [https://jsfiddle.net/wc0o27rt/1/][1]

Thank you!
