I'd like to fill the region below a stairs!()
plot (between the stairs and the x axis) in order to get something like the gray area in the image, but with a specific % transparency.
A somewhat hacky way (digs into the stair plot to get the graphed points):
function stairpts(s)
pts = s.plots[1].converted[1][]
[p[1] for p in pts], [p[2] for p in pts]
end
s = stairs!(xs, ys, step=:post)
xs′, ys′ = stairpts(s)
band!(xs′, 0*ys′, ys′, color=(s.color, 0.25)) # 0.25 alpha
Creating a recipe for this type of plot is probably better.
