How can I create a shaded plot like the figure sample shown here? They are to delineate one zone in darker grey and another one in lighter grey. Please provide sample code if possible.

Ran in:
Try something like this, using patch —
x = linspace(70, 130, 12);
y = rand(2, numel(x));
figure
plot(x, y)
grid
hold on
patch([85 105 105 85], [[1 1]*min(ylim) [1 1]*max(ylim)], [1 1 1]*0.8, 'FaceAlpha',0.5, 'EdgeColor','none')
patch([105 115 115 105], [[1 1]*min(ylim) [1 1]*max(ylim)], [1 1 1]*0.6, 'FaceAlpha',0.5, 'EdgeColor','none')
hold off
Experiment to get the desired result.
