How to add two vertical lines to plot and color between them?

Hi,

I want to highlight a period in my plot by adding two vertical lines and coloring between them. Any ideas on how to do that?

Here's one way:

figure

%Plot something
plot(1:10)

% Add lines
h1 = line([2 2],[1 10]);
h2 = line([5 5],[1 10]);

% Set properties of lines
set([h1 h2],'Color','k','LineWidth',2)

% Add a patch
patch([2 5 5 2],[1 1 10 10],'r')

% The order of the "children" of the plot determines which one appears on top.
% I need to flip it here.
set(gca,'children',flipud(get(gca,'children')))

Perfect!

Just one more question: instead of using the color 'r' (red), how can I use a light gray color? In fact my graph has three different patches, so I wanted to use different shades of gray...

Cheers!

You can encode an RGB value, by replacing 'r' with an RGB vector with values between 0 and 1.

gray = [0.4 0.4 0.4];
patch([2 5 5 2],[1 1 10 10],gray)

Works Great! Thanks.

How can I add grid to the figure which is not covered by the patch color?
