I have file with the breathing of sick people. These breathing sounds have wheezes in it. I had the plot drawn. I also have the start and end indexes of wheezing. How can I mark these indexes on the plot?

If (x,y) is your data and id1 and id2 are the indices. Use:
plot(x,y,'b')
hold on
id = [id1 id2] ;
plot(x(id),y(id),'*r')

You could use the MarkerIndices property of the line object returned by plot or you could use xline depending on how you want those points marked.
x = 0:360;
y = sind(x);
plot(x, y, 'ro-','MarkerIndices', (0:45:360)+1)
figure
plot(x, y, 'r-')
for multiplesOf45 = 0:45:360
xline(multiplesOf45)
end

My plot is this. For example first wheeze starting at 1063 and end at 7952. My question is how can I mark points 1063 and 7952 only? These indexes are only in x axis .The region between this indexes will give me the wheezing of an patient. Can you help me with this?
