Hello, I'd really like to know how to calculate the area beneath a shape like this:
So from the outer borders to x-axis. Since the values are repeating I reckon trapz() doesn't work.

Read about polyarea, convhull.
convhull gives you coordinates of the points which defines your shape, with these corodinates youc an use polyarea.

I thought there'd be a more elegant solution like with
area(Yp,Xp)
I can cast the shadow of the shape, but nothing more.
Well, I keep it simple and extract a curve manually as u advised. This works at the least.
