I want to make this graph from largest to smallest. How can I do this?
Airpollution = readtable ('Location vs No2.xlsx');
x = categorical(Airpollution{:,1});
y = Airpollution{:,2};
bar(x,y)
xlabel('Cities');
ylabel('Concentration of No2');
title(['Cities in Andha Pradesh, India vs Maximum concentration of No2 (2010)']);

Try
Airpollution = readtable ('Location vs No2.xlsx');
x = categorical(Airpollution{:,1});
y = Airpollution{:,2};
% Sort by decreasing y value.
[sortedY, sortOrder] = sort(y, 'descend');
% You must sort x the same way so you don't lose correspondences.
sortedX = x(sortOrder);
% Plot the bar chart from largest to smallest.
bar(sortedX, sortedY)
xlabel('Cities');
ylabel('Concentration of NO_2');
title(['Cities in Andha Pradesh, India vs Maximum concentration of No2 (2010)']);
