please consider this sample code:
data = [0,2,9,2,5,8,7,3,1,9,4,3,5,8,10,0,1,2,9,5,10];
Why this histogram plots the data points 0 & 1 with frequency 4 (on Y-axis),when in fact 0 & 1 appear two times in data.

data = [0,2,9,2,5,8,7,3,1,9,4,3,5,8,10,0,1,2,9,5,10];
y= histc(data,d)
Look at
help hist
N = hist(Y) bins the elements of Y into 10 equally spaced containers and returns the number of elements in each container
help histc

You have 11 different values (0 through 10) but only 10 bins (default number to use if you do not specify the number in a hist() call).
