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?

Accepted answer

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')))

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)
