I really like that you want to know the specifics of plotting multiple graphs within a single tiled layout. I understand that you have three main questions, here's how you can approach them:
1. Adjust space between subplot titles and the graphs. Instead of using the default title, adjust the vertical position manually:
t = title('Title Name');
t.Units = 'normalized';
t.Position(2) = 1.03; % Moving the title slightly above the plot. You can change this to desired value.
2. Show the legend only in the 6th tile. Use an empty tile and attach the legend explicitly:
nexttile(6)
ax = gca;
cla(ax); % Clear any plot
axis off; % Hide axes
legend(ax, barHandle, {'Category 1', 'Category 2', ...}, 'Location', 'northwest');
title('Legend');
3. Add percentage labels and total on top of stacked bars. Loop through each bar and use text to annotate percentages and totals:
for i = 1:size(data,1)
y_base = 0;
for j = 1:size(data,2)
val = data(i,j);
percent = val / sum(data(i,:)) * 100;
if percent > 5 % skip tiny segments
text(i, y_base + val/2, sprintf('%.1f%%', percent), ...
'HorizontalAlignment', 'center', 'FontSize', 8);
end
y_base = y_base + val;
end
% Add total value above the stack
text(i, y_base + 0.03*max(sum(data,2)), ...
num2str(sum(data(i,:)), '%.0f'), ...
'HorizontalAlignment', 'center', 'FontWeight', 'bold');
end
Using these fixes, I have obtained the plot you desired, attaching it for reference.
