Trying to make a respectable looking Hist3 plot and having big difficulty

[Tim Pierce]

Trying to understand why the Octave-Forge Hist3 Example looks like this: (see picture at bottom of online help)

        https://octave.sourceforge.io/statistics/function/hist3.html

But when I run that exact code mine looks like this

When I run it on my data it looks just as bad. I would love to showcase these 3D bars showing that Octave rivals some of our overpriced BI software but right now I'm struggling with getting things to look passable

Would LOVE any help to get this looking okay
