How can I create axis labels with subscripts and greek letters?

I am trying to replicate the style of this graph (see attached image), the only parts I am missing are the axis labels and filling in the shaded area between the lines. I've looked into LaTex but havent been able to recreate the same style with it.

The following should work:

y1 = 1:10;
y2 = (1:10)*0.5;
x = 1:10;
plot(y1); hold on;
plot(y2);
xlabel('Size (\delta)');
ylabel('\kappa');
X = [x, fliplr(x)];
inBetween = [y1, fliplr(y2)];
fill(X, inBetween, 'g');

The above code gave me the following output

The problem I'm having now is the shaded region covers the 'mean' line. It works perfect with the two, just not the third middle line.

Try plotting the last plot after shading as shown below:

    y1 = 1:10;
    y2 = (1:10)*0.5;
    ymean = (y1+y2)/2;
    x = 1:10;
    plot(y1); hold on;
    plot(y2);
    xlabel('Size (\delta)');
    ylabel('\kappa');
    X = [x, fliplr(x)];
    inBetween = [y1, fliplr(y2)];
    fill(X, inBetween, 'g');
    plot(ymean);

You would get something like this

Alternately, one of:

• uistack() to move the relative drawing order of the objects; or
• set the mean line to have a slightly positive Z component so that it is above the shaded area; or
• set alphadata on the shaded area so that the line is visible through it.
