I have starting and ending indexes. I atteched these indexes in that files. I also have a plot. I want to put a horizental bar between vertical lines. Can you help me? It is my code

Sound=structWheeze(1,1).SoundData;
starting=structWheeze(1,1).Properties.WS_new; 
ending=structWheeze(1,1).Properties.WE_new; 
x = linspace(0, 144000 , 144000); 
figure
plot(x,Sound) 
hold on
plot(x(starting[1 1]).',(ones(size(starting,1),2).ylim).', 'g', 'LineWidth',2); %green markers
plot(x(ending[1 1]).', (ones(size(ending,1),2).ylim).', 'r', 'LineWidth',2); %red markers
hold off
grid

We do not have the plot of the signal, however drawing the horizontal lines between the starting green lines and the ending red lines is straightforward.

WS_new_array = [1063; 17565; 21359; 36899; 55411; 70245; 90088; 102232; 114892; 119569; 123811];

WE_new_array = [7952; 19385; 26744; 45315; 61905; 77760; 94105; 111387; 117453; 122765; 126968];

figure

plot((WS_new_array*[1 1]).', (ones(size(WS_new_array))*ylim).', 'g')

hold on

plot((WE_new_array*[1 1]).', (ones(size(WE_new_array))*ylim).', 'r')

plot([WS_new_array WE_new_array], [1 1]*0.8, '-k', 'LineWidth',2)

hold off

I plotted them at a y-value of 0.8 here, as solid balck lines with a line width of 2. Change those to whatever value you want.
