band (patch) of varying width?

Hi guys, I have an idea for a visualization and I'm wondering if you all think it would be possible with patch or similar. Essentially I'd like to create a patch which operates like a violin plot, where for example greater uncertainty would be a wider section, and less uncertainty would be narrow. I can't use the existing violin on FEX because I would need this band/patch to be (in this example) 72 long.

I've generated some random uncertainty data, but how would I go about setting the width or filling a patch with it? Some sort of moving window-like function? Patches get messy quick. Any brilliant thoughts welcome :)

u=rand(72, 1)

Thanks a bunch.

It would be possible to create a violin plot but you'd have to come up with the outline yourself, unless there's a built in function for violin that I'm not aware of. Once you have the outlines you can display them with fill() or patch().
