X and Y axis alignment

15 views (last 30 days)
How would I be able to make a bar graph with the colours of Y values over 30 blue and the colors of Y values under 30 red. I would also like to name to place a title (title) that is bold and has a font of 16px and a Y and X axis with the names(y_axis, x_axis ) plot on the bar graph how would I be able to do those?
X = categorical({'Small','Medium','Large','Extra Large'});
X = reordercats(X,{'Small','Medium','Large','Extra Large'});
Y = [10 21 33 52];
Y_over = find(Y>30)
Y_under=find(Y<30)
y_axis = 'Y plots'
x_axis = 'X plots'
title = 'Comparing Y and X over intervals'
bar(X,Y)

Something like this?
X = categorical({'Small','Medium','Large','Extra Large'});
X = reordercats(X,{'Small','Medium','Large','Extra Large'});
Y = [10 21 33 52];
ylabel('y-axis','FontSize',12)
xlabel('x-axis','FontSize',12)
title('Comparing Y and X over intervals','FontSize',16);
% threshold value
threshold = 30;
% plot bar one by one
figure(1)
hold on
for ii = 1:1:length(X)
b = bar(X(ii), Y(ii));
if (Y(ii) >= threshold)
set(b, 'FaceColor', 'r');
else
set(b, 'FaceColor', 'b');
end
end
