How to construct unequal width histograms with Matlab?
12,852
Solution 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)])
Solution 2
2 solutions:
- Specify bin centers with the 2nd argument to hist.
- Specify bin Edges with with the 2nd argument to histc. This function takes some further processing since it does not generate the graph directly - follow the link for a usage example.
