How do I set a background Color in Plots?

Hi , I wanted to know as to how I can go about changing the background color in a plot. The default background color of a plot is White. Some info on how to keep the color of data points' constant and change only background color of plot will be of great help. Thanks !

The patch function is one way to do it:

x = linspace(0,10*pi);
y = sin(x).*cos(50*x);

xl = [min(x)  max(x)];
yl = [min(y)  max(y)];

figure(1)
patch([xl fliplr(xl)], [yl(1) yl(1) yl(2) yl(2)], [0.5 0.8 0.9])
hold on
plot(x, y, '-b')
grid
hold off
axis([min(x)  max(x)    min(y)  max(y)])
