I want to draw a plot with the points:
y >= f(x)
where f(x) is some function I define.
Using an x-y plot, I can draw only the function:
y = f(x)
Using an area plot, I can draw an area of a single column (i.e. not y as a function of x). Is there any way I can fill the area above the x-y curve?
EDIT: When the x values are linear (i.e. 0, 1, 2, ...) then it is easy to fill the area below the curve by using an area plot with the y series only, like here (right):
