Say that I have defined a line:

```julia
using Plots
x_vals = 1:10
y_vals = sqrt.(x_vals)
plot(x_vals, y_vals)

```

Is there a way that I can color the plot plane, so that the area below the line have one color and the are below have another one?

The solution is to use the `fillrange` kwarg to `plot`.
