# Fill the area below/above an x-y curve

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?
