I'm trying to make a 3D stacked bar graph from a 4-column matrix or 4D array (let's call the columns x-y-z-e). For any x-y-e combo, there are multiple z values (sort of like a stacked 3D bar graph). I want to make a plot where the Z values are a gradient, instead of discrete stacks and e as a color scale
Here's an example from different software... I'm having trouble replicating it.
Thanks for any help, and apologies if this solution is out there and I have simply missed it
