I'm trying the following code (Mathworks example) but I only want the LineStyle of top curves to be as specified (like the attached figure). Also I want the xaxis strats from 0 instead of 1.

Y = [1, 5, 3;
     3, 2, 7;
     1, 5, 3;
     2, 6, 1];
figure
area(Y, 'Linewidth', 2, 'LineStyle', '-.')

Here are two options with slightly different outcomes.

Option 1

Modify the upper line only

Y = [1, 5, 3;
     3, 2, 7;
     1, 5, 3;
     2, 6, 1];
figure()
area(Y)
hold on
plot(sum(Y,2),'Linewidth', 2, 'LineStyle', '-.')

Option 2

Modify the line that surrounds the entire outline of the upper area object.

Y = [1, 5, 3;
     3, 2, 7;
     1, 5, 3;
     2, 6, 1]; 
figure()
h = area(Y);  % get the area object handles
set(h(3), 'Linewidth', 2, 'LineStyle', '-.')
