How do I get values on top of my bar plot?

I have data that I want to have shown in groups of three. How can I get the values Diff onto the bar plot? I have tried various ways but can't get it right...

Diff = [minD1 maxD1 meanD1; minD maxD meanD; minD2 maxD2 meanD2; minD3 maxD3 meanD3; minD4 maxD4 meanD4]*10^4;

figure
name = categorical({'100 ul', '200 ul', '500 ul', '750 ul', '1000 ul'});
name = reordercats(name,{'100 ul', '200 ul', '500 ul', '750 ul', '1000 ul'});
bar(name, Diff)
ylabel('Diffusion coefficent (10^-^4)')
legend('min D','max D','mean D')
grid on 
grid minor

Can you show an example of what type of bar graph you want?

[Jenni]

This type! :)

Did you try text? Use for loop

[Jenni]

I tried, but I could not get it to work... I got all text on each staple.

See this example

% Diff = [minD1 maxD1 meanD1; minD maxD meanD; minD2 maxD2 meanD2; minD3 maxD3 meanD3; minD4 maxD4 meanD4]*10^4;
Diff = rand(5, 3);
name = {'100 ul', '200 ul', '500 ul', '750 ul', '1000 ul'};
figure;
ax = axes();
b = bar(1:5, Diff);
ylabel('Diffusion coefficent (10^-^4)')
legend('min D','max D','mean D')
grid on 
grid minor
ax.XTickLabel = name;

barNames = {'a', 'b', 'c'};
x_diffs = [-0.25 -.05 0.2]; % x-location of bars relative to middle bar
y_diff = 0.02; % height of text above the bar
for i = 1:numel(b)
    text(b(i).XData+x_diffs(i), b(i).YData+y_diff, barNames(i));
end

Thank you! Can I use this to have different names on each collumn?

[Ameer Hamza]

The above code shows a general example. You can adapt it according to your requirements. For example, the following shows how to use different names for each bar.

% Diff = [minD1 maxD1 meanD1; minD maxD meanD; minD2 maxD2 meanD2; minD3 maxD3 meanD3; minD4 maxD4 meanD4]*10^4;
Diff = rand(5, 3);
name = {'100 ul', '200 ul', '500 ul', '750 ul', '1000 ul'};
figure;
ax = axes();
b = bar(1:5, Diff);
ylabel('Diffusion coefficent (10^-^4)')
legend('min D','max D','mean D')
grid on 
grid minor
ax.XTickLabel = name;

barNames = {'a', 'b', 'c';
            'd', 'e', 'f';
            'g', 'h', 'i';
            'j', 'k', 'l';
            'm', 'n', 'o'};
x_diffs = [-0.25 -.05 0.2]; % x-location of bars relative to middle bar
y_diff = 0.02; % height of text above the bar
for i = 1:numel(b)
    text(b(i).XData+x_diffs(i), b(i).YData+y_diff, barNames(:,i));
end

Thank you very much! It works fine now!

I am glad to be of help!
