MATLAB: How to rotate xaxis labels (bar graph)

axis labelsbar

I'm having a very difficult time figuring out how to rotate the x-axis labels on a bar graph. If I have the code at the bottom, I get the error Undefined function or variable 'rotateXLabels'.

Error in Test1 (line 5) rotateXLabels(gca, 45);

numbers = magic(5) labels = {'label 1', 'label 2', 'label 3', 'label 4', 'label 5'}; bar(numbers(:,1)) set(gca, 'XTickLabel', labels) rotateXLabels(gca, 45);

Does anyone know how to rotate the axis labels? Thanks

MATLAB: What would the bar graph coding be

I am not certain what you want, so here are two possibilities:

D = load('histo1.mat');
histo1 = D.histo1;
figure(1)
bar(histo1);
set(gca, 'XTickLabel', {'Group 1', 'Group 2', 'Group 3', 'Group 4', 'Group 5', 'Group 6'})
figure(2)
bar(histo1);
legend('Group 1', 'Group 2', 'Group 3', 'Group 4', 'Group 5', 'Group 6')

Be sure to look at both figures! The code in each labels the ‘group’ data differently.

If you organize your data as :

%     A1  A2  A3  A4
X = [ 3,  7,  0,  0;  % Label 1
      3, 20,  7,  0;  % Label 2
      3,  4,  0,  8]; % Label 3

You just need:

  bar(X, 'stacked');

If you wish to make it look similar to your example:

labels = {'Label 1', 'Label 2', 'Label 3'};
attributes = {'A1', 'A2', 'A3', 'A4'};
figure;
bar(X, 'stacked');
set(gca,'XTickLabel', labels);
set(gca, 'YGrid', 'on', 'XGrid', 'off');
legend(attributes, 'Location', 'NorthOutside', 'Orientation', 'Horizotnal');
colormap([68 114 196;165 165 165;91 155 213;38 68 120] / 255);
ylim([0, 35]);
title('XX');

Furthermore, assuming the data is stored in three variables (i.e., the columns)

Label = {'Label 1', 'Label 1', 'Label 2', 'Label 2', 'Label 3'};
Attribute = {'A1', 'A2', 'A2', 'A3', 'A1'};
Observations = [3, 6, 4, 8, 9];

The "organization" of the data can be done with

labels = {'Label 1', 'Label 2', 'Label 3'};
attributes = {'A1', 'A2', 'A3', 'A4'};
X = zeros(numel(labels), numel(attributes));
for k = 1:numel(Observations)
  i = ismember(labels, Label{k});
  j = ismember(attributes, Attribute{k});
  X(i, j) = X(i, j) + Observations(k);
end
