I plot a row of image containing its pixel values... for example row = 110....

http://farm3.static.flickr.com/2763/4318073947_3de891d114_o.jpg

the code is..

plot(I7(110,1:640), 'DisplayName', 'I7(110,1:640)', 'YDataSource', 'I7(110,1:640)'); figure(gcf)

but i want to add a marker on the graph on certain x-axis values.. (like..24...30...50..)

any marker will do.. 'o', '*', or 'x'...

so that the graph looks like this...

A, B, C, D, E, F refers to the position of the marker i want them to be...

how can i do this?

thanks...

This is how I'd try it:

Plot the full curve
get a smaller vector with only the coordinates of the markers that you
want to display
put "hold on" so you don't destroy the curve.
plot the markers, like plot(x_markers, y_markers, 's')
with a for loop, use the text() command to place a label next to each
marker.
