How to label each line in the plot

Hello everyone i hope you are doing well. I want to label y axis with the value i get from

Value= unique(whiteLineRows1);

but when i plot it gives the Value= as in the image attached

How can i plot the value on each line

path = 'C:\Users\DELL\Documents\MATLAB\Examples\R2021b\phased\ModClassificationOfRadarAndCommSignalsExample\NewDataset\DatasetGeneration\Detection\ImageDetection\imageclass_001001.png';
rgbImage = imread(path);
[rows, columns, numberOfColorChannels] = size(rgbImage);
if numberOfColorChannels > 1
	grayImage = rgbImage(:, :, 3);
else
	grayImage = rgbImage;
end
[rows, columns, numberOfColorChannels] = size(rgbImage);
mask = grayImage >= 128;
[labeledImage, numRegions] = bwlabel(mask);
props = regionprops(labeledImage, 'Area', 'Centroid');
allLengths = [props.Area];
centroids = vertcat(props.Centroid);
whiteLineRows1 = centroids(:, 2);
Value= unique(whiteLineRows1);
hold on
Levels=length(Value);
for k = 1 : Levels
str = sprintf('Value %d', Value(k))
yline(Value, 'LineWidth', 2, 'Color', 'r','Label',str);
hold off
end

The main problem in the image is that the values are superimposed. This can be fixed by using an index into the Values array for each line:

for k = 1 : Levels
    str = sprintf('Value %d', Value(k))
    yline(Value(k), 'LineWidth', 2, 'Color', 'r','Label',str);   % add index into Value
    hold off
end
