MATLAB: Put bars in bar graph in ascending order

ascendingbarbargraphorder

i want to put this in order from smallest to largest population instead of alphabetical order. How can I do this?
clc
clear all
close all
%reading the file
[numbers text]=xlsread('homelesspopinamerica.xlsx');
%manipulating withthe data and storing it at our convenience
statenames=text(2:51,1:2);
pop=numbers(1:50,:);
states=statenames(:,2);
state=statenames(:,2);
homepop=pop(:,2);
homeperc=pop(:,4);
totpop=pop(:,3);
states=categorical(states);
%plotting
figure
bar(states,homepop)
xlabel('States', 'Fontsize', 18)
ylabel('Numer of Homeless Persons (Millions)', 'Fontsize', 18)
title('HOMELESSNESS IN AMERICA 2017', 'fontsize', 24);
set(gcf,'color','w');
set(gcf, 'Units', 'Normalized', 'OuterPosition', [0 0 1 1]);
%turn on grid lines
set(gca,'XGrid','off')
set(gca,'YGrid','on')

Best Answer

If you have a look at https://www.mathworks.com/help/matlab/ref/categorical.html then you can see that when you construct the categorical array, you can pass "valueset" as the second parameter, and that the categories would be ordered according to the values in valueset. So you could pass the populations of the states in the second parameter, and the corresponding state names in the third parameter, and that would create names sorted by population.
