I have the following figure
I want to change the color of text like the color of its bar, for example 100 => blue, 83.3 => red ...etc
Also I want to text appear Vertical not Horezental.
This is the code:
for k1 = 1:4
ctr(k1,:) = bsxfun(@plus, Bar(k1).XData, Bar(k1).XOffset'); % Note: ‘XOffset’ Is An Undocumented Feature, This Selects The ‘bar’ Centres
ydt(k1,:) = Bar(k1).YData; % Individual Bar Heights
end
ctr
% ydt
for k1 = 1:size(ctr,2)
format short
text(ctr(:,k1), ydt(:,k1), sprintfc('%.1f',ydt(:,k1)), 'HorizontalAlignment','center', 'VerticalAlignment','bottom')
end

Ran in:
data = rand(4,4);
data(:,[3 4]) = 0;
Bar = bar(data);
[m,n] = size(data);
ctr = zeros(n,m);
ydt = zeros(n,m);
for k1 = 1:n
ctr(k1,:) = bsxfun(@plus, Bar(k1).XData, Bar(k1).XOffset'); % Note: ;XOffset’ Is An Undocumented Feature, This Selects The ‘bar’ Centres
ydt(k1,:) = Bar(k1).YData; % Individual Bar Heights
end
ctr
ctr = 4×4
0.7273 1.7273 2.7273 3.7273 0.9091 1.9091 2.9091 3.9091 1.0909 2.0909 3.0909 4.0909 1.2727 2.2727 3.2727 4.2727
% ydt
for k1 = 1:n
for k2 = 1:m
% format short
text(ctr(k1,k2), ydt(k1,k2), sprintfc('%.1f',ydt(k1,k2)), ...
'Color',Bar(k1).FaceColor, ...
'Rotation',90, ...
'HorizontalAlignment','left', ...
'VerticalAlignment','middle')
end
end
