So im trying to modify the code here:
My modified code is attached to this question.
my problem is that the color in my histogram plot is not according to color. It does not have a sequence of color since the black bar is near the center when it is supposed to be at the right most.
Original image is:

Histogram of the image is:

Also, follow up question. How can i extract using the histogram plot a specific boundary of color. Like example i want to extract from the original image the pixels with yellowish color. How can i do that? Thank you so much!

It's best if you ask the author about why his program behaves that way. Are you sure the function expects a 3D color image?
I have several color segmentation routines in my File Exchange to help you with 'i want to extract from the original image the pixels with yellowish color" http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862

Any of them that say "color segmentation" or "color detection" in the title.
