Question

I would like to construct a histogram with unequal bins (intervals)..Matlab construct only histograms with equal bins as if it’s a diagram..!!!

Please help me…thanks a lot!!

Answer 1

Here’s an example:

x = randn(100,1)*3;           %# some random data
e = [-10 -5 -3 -1 1 2 3 20];  %# edges of intervals:  e(i) <= x < end(i+1)
c = histc(x,e);               %# get count in each interval
bar(e, c, 'histc')            %# bar plot
set(gca, 'xlim',[e(1) e(end)])
