Plot continuous standard deviation with shaded color

I would like to plot angle mean evolution during a jump with the continous standard deviation like this example :

For the moment, I can't color the standard deviation area :

Do you know how I can plot my standard deviation as a shaded area ?

Thank you.

Hi Jeanne,

As per my understanding, you want to shade the area representing the standard deviation with a different colour.

You can consider the following example to fill colour between two different plots:

x = 1 : 20;
% curve1 and curve2 representing the data and its deviation
curve1 = sin(x);
curve2 = sin(x) + 0.5;
plot(x, curve1, 'r', 'LineWidth', 2);
hold on;
plot(x, curve2, 'b', 'LineWidth', 2);
x2 = [x, fliplr(x)];
inBetween = [curve1, fliplr(curve2)];
fill(x2, inBetween, [1 0.7 1]);
