Plot with background colors depending on the y values

This is my data

data = [1 2 3 4 5 6 7 8 9 10 ; 0.2 0.5 0.1 0.02 0.04 3 6 7 0.01 0.05];

In fact, I have a similar data frame but with a large amount of values (it is about 25 000 rows and 2 columns (x and y))

And I want to obtain this graph in which the background color depends on the yvalue (here : blue for yvalue < 1 and brown for yvalue > 1)

Thanks for help !

data = [1 2 3 4 5 6 7 8 9 10 ; 0.2 0.5 0.1 0.02 0.04 3 6 7 0.01 0.05];
x = data(1,:) ; y = data(2,:) ;

[X,Y] = meshgrid(x,y) ;

pcolor(X,Y,Y) ; shading interp 
hold on
plot(x,y,'b')

It is not really that I want

To rephrase : I want to attribute, to each x value, a specific color which depends on the y value

The code does what you shown in image...why don't you show a pictorial example of what you expect.

You can also use patch() or fill() in place of pcolor().

I got it ! But I used bar() (to create histogram) instead of patch() or pcolor()
