How can I use horizantal lines instead of vertical lines to connect certain points?

ses=structWheeze(2,1).SoundData;
flow=structWheeze(2,1).Flow;
 
WSFS=structWheeze(2,1).Properties.WS_SF;
WEFS=structWheeze(2,1).Properties.WE_SF;
WS_new_array=structWheeze(2,1).Properties.WS_new; %enables to define wheeze starting indices
WE_new_array=structWheeze(2,1).Properties.WE_new; %enables to define wheeze ending indices
x = linspace(0, 144000 , 144000); 
figure
plot(x,ses) %enables to plot the sound
hold on, plot(flow,'c')
%  legend('ses','flow')
hold on
plot(x(WS_new_array*[1 1]).',(ones(size(WS_new_array,1),2).*ylim).', 'g', 'LineWidth',2); %green markers
plot(x(WE_new_array*[1 1]).', (ones(size(WE_new_array,1),2).*ylim).', 'r', 'LineWidth',2); %red markers
plot(x(WSFS*[1 1]).',(ones(size(WSFS,1),2).*ylim).', 'y', 'LineWidth',2); %green markers
plot(x(WEFS*[1 1]).',(ones(size(WEFS,1),2).*ylim).', 'k', 'LineWidth',2); %green markers
hold off

"replace the red and green lines with a horiz[o]ntal bar"

xb=[x(WS_new_array) flip(x(WE_new_array))];
yb=ylim*ones(size(xb));
hP=patch(xb,yb,[0.5 0 0],'FaceAlpha',0.1);

salt to suit...

Same idea for other direction, of course.

Thank you for your answer but I received this error;

Matrix dimensions must agree.

Error in bar (line 14)

yb=ylim.*ones(size(xb));

Well, I just tried to decipher sizes from your code which is very tough to read...

What you need are x,y vectors of length 4 from L to R, R to L in order which trace the outlines of the rectangle to fill in.

x(WS_new_array*[1 1]).'

looks like it should be a two-vector of the two X positions; multiplying by 1 is a no-op and doesn't matter about whether is row or column.

So,

xb=[x(WS_new_array) flip(x(WE_new_array))];

surely looks like should be a four-vector.

I presumed

WS(1)             WS(2)  (@ Elevation Y1)





WE(2)             WE(1)  (@ Elevation Y2)

would be representative of the locations if plotted on an XY grid.

If that's not the case, then get the proper points out of your X,Y vectors to produce those points in that order so they create a closed path.

So how can I turn these vertical lines into a single horizontal line instead of making them bars? eg a single horizontal, red line for green and red lines and single, horizantal yellow line for yellow and black lines.

[Walter Roberson]

I do not see where you have defined the coordinates you want the horizontal lines to be drawn at.

[Serhat Sayim]

I attached the starting coordinates and ending coordinates. green lines' coordinates are startingindexes.m, red lines' coordinates are endingindexes.m
