Dear all, I draw a histogram for an array called (single{K}), using the following code, it seems ok but what I need to do is how to determine the ranges of load bins before drawing it? i already defined the number of bins which is 38, but how can i tell matlab to set the bins with fixed increments, such as: 3000 to 40000 lb at 1000 lb interval? attached is my histogram which needs help
figure
histogram(single{K}, 38)
xlabel('Load in Kips')
ylabel('Counts')
title(['ALS for C9 Single For Month ',num2str(months),' ', 'Station' ,' ', num2str(stations)])

Use bin edges:
edges = [-inf, 3000:1000:40000, inf];
histogram(single{K}, edges);

It is. It's just a histogram where all the bins but one are empty.
Let's say I were to ask everyone who posted on MATLAB Answers today for their year of birth and I created a histogram. I create one bin is for everyone born before 2020 and bins for everyone born in 2020, 2021, 2022, ... 2100. That histogram is going to look very similar to yours, since it's highly unlikely that anyone posting here today was born after 2020. Though if we do have any time traveling posters, welcome to the past. I'd love to talk to you.
Experiment with the different options for the BinMethod option of histogram and look at the bounds of your data. Or just let histogram try to choose "nice" bins for you.
