X-axis label on two rows

Question

str = {\'HS31\'; \'HS31 (Ridotto)\';
    \'Dax85\';\'Dax85 (Ridotto)\';
    \'FTSE89\';\'FTSE89 (Ridotto)\';
    \'SP98\';\'SP98 (Ridotto)\';
    \'Nikkei22\';\'Nikk         


        

Answer 1

Whats missing in the answer by Divakar is actually a solution with two (or more) rows. You can simulate it with text boxes at certain positions.

str = {'HS31'; 'HS31 (Ridotto)';
    'Dax85';'Dax85 (Ridotto)';
    'FTSE89';'FTSE89 (Ridotto)';
    'SP98';'SP98 (Ridotto)';
    'Nikkei22';'Nikkei225 (Ridotto)';
    'SP457';'SP457 (Ridotto)';
    'Russ1318';'Russ1318 (Ridotto)';
    'Russ2151';'Russ2151 (Ridotto)';
    'Eurostoxx';'Eurostoxx (Ridotto)';
    'Ftse';'HS31 (Ridotto)';
    'Mibtel';'Mibtel (Ridotto)';
    'SP';'SP (Ridotto)';
    'Nasdaq';'Nasdaq (Ridotto)';};
bar(rand(26, 1));
% clear labels existing so far
set(gca, 'XTickLabel', {});

% parameters
spacing = 0.03; % between different rows of labels and between x-axis and label
rows = 2; % number of rows in staggered layout
heightAdjust = 0.1; % reduce height of figure to make space for vertically stacked labels

pos = get(gca,'Position');
set(gca, 'Position', pos+ [0 heightAdjust 0 -heightAdjust] )

ylim = get(gca, 'YLim');
for i = 1 : length(str) % for all labels
    % compute y position of label (depends on x, therefore staggered)
    y = ylim(1) - spacing - spacing * mod(i - 1, rows);
    % print text box at correct position to simulate label
    text('Units', 'Data', 'Position', [i, y], 'HorizontalAlignment', 'center', 'String', str(i));
end

The number of rows and some spacing parameters have to be set manually. And it looks like this when the figure is maximized.
