How to sort data in a bar plot based on its values on Y-axis?

Hi there,

I am working on a bar graph as shown below.

I would like to sort them 'descending' so that LS713A (the highest) is plotted at the left and then CH12B, CH202A, SC762B and SC748A (the lowest) respectively.

I tried to use reordercats but it does not work. Could you please give some example(s)?

Thank you and best regards.

I assume the x-data are categorical, because otherwise this is straightforward.

Perhaps this —

x = 1:5;
y = rand(1,5);
xlbl = categorical(["A","B","C","D","E"]);

figure
bar(xlbl,y)
title('Original')

Ax = gca;
% get(Ax)

xv = Ax.Children.XData;
yv = Ax.Children.YData;
[~,idx] = sort(yv, 'descend');
xv = reordercats(xv, idx);

figure
bar(xv(idx), yv(idx))
title('Sorted')

.
