Hey, I have data that I am plotting a histogram with, and I want to center my histogram on the mean, with six bins (i.e 3 on each side). I need that each bin is the width of the standard deviation. Thanks in advance for any replies. Cheers, Amina

Hi Amina,
You can specify the bin location in hist function, for example
x = rand(1024,1);
sigmax = std(x);
mx = mean(x);
binloc = (-2.5:2.5)*sigmax+mx;
hist(x,binloc)
More details can be found at
doc hist
