In this figure, say a graph is plotted plot(a,b). First, how can I shade full graph in gray color (either left or right side) and then how to shade a small zone?

Try something like this —
y = linspace(0,10); % Assume Row Vectors (Actual Data Not Provided)
x = randn(size(y));
yg = (y >= 2) & (y <= 4); % Special Shading Region
plot(x, y)
xl = xlim;
hold on
patch([x, ones(size(x))*xl(2)], [y, flip(y)], [1 1 1]*0.75)
patch([x(yg), ones(size(x(yg)))*xl(2)], [y(yg), flip(y(yg))], [0 1 1]*0.85, 'EdgeColor','none')
hold off
If the vectors are column vectors, the easiest way to use my code with them would be to transpose them to row vectors and then use my code without significant changes to it. Define the ‘yg’ logical vector appropriately for the available data.
