Filling a white space in plot with another color

Hello guys,

just want to ask if it is possible to change the white color in plot

to look something like this (it was filled in MS Paint so don't mind the "stairs" efect)

I tried to look on the internet but found nothing about it. Just want to know if it is even possible to do something like this.

It is not possible in a direct way, but you can do things with patch to get a similar result:

t=linspace(0,5*pi,1000);
y=abs(sin(t));
plot(t,y)
ylim([0 1.1])

lims=axis;
x_area=[t lims(2) lims(2) lims(1) lims(1) t(1)];
y_area=[y lims(3) lims(4) lims(4) lims(3) y(1)];

hold on
patch(x_area,y_area,'k')

Works like a charm, thank you.
