Shade the area under a anonymous function

Im trying to visualize the area between my anonymous function and the x-axle but can't find a way of doing so.

Does someone have a method for this?

code ?

The only thing i have done is that i created an anonymous function and then plot it using fplot()

 f=@(x) sin(1-x^3)
fplot(f)

f=@(x) sin(1-x.^3)
x=0:0.001:2*pi;
area(x,f(x))

Now i tried to only show the area from -1 to pi but when i do that my x-axel is weird, showing x=0 to x=4500 but the graph is correct. How could i adjust the x-axel to show accurate?

I changed the x vector to this and then used area(f(x)):

>> x=-1:0.001:pi;
>> area(f(x))

Tried to attatch a picture to this comment but wasnt able.
