MATLAB: Histogram with two sets of data

histogramr2010a

Hello, I want to make an histogram exactly like the image here. Have you an idea ?

Best Answer

Use the bar function with the 'grouped' option. The error bars and the comparison lines between the plotted bars are a bit more difficult, and the code the plot them depends on whether you are using R2014a or earlier, or R2014b or later.

Try this:

PPdata = [960.6 960.3 960.4; 960.5 960.7 960.7];
PPerr = [0.4 0.4 0.5; 0.1 0.1 0.1];
% PPx=categorical({'\it CL','\it DM'});
figure
hBar = bar(PPdata);
hBar(1).XData
hold on
for k1 = 1:size(PPdata,2)
    ctr(k1,:) = bsxfun(@plus, hBar(k1).XData, hBar(k1).XOffset');   % Note: ‘XOffset’ Is An Undocumented Feature, This Selects The ‘bar’ Centres
    ydt(k1,:) = hBar(k1).YData;                                     % Individual Bar Heights
end
hold on
errorbar(ctr, ydt, PPerr.', '.r')
PPx=categorical({'\it CL','\it DM'});
set(gca, 'XTickLabel', PPx)
title('Peak position by region')
ylim([960.2 961.2]);
legend({'Cervical','Cuspal','Intercuspal'},'Location','southoutside')

MATLAB: How to display a value on bar

Try this (if you have R2014b or later):

y1 = [2 2 3; 2 5 6; 2 8 9; 2 11 12];
hBar = bar(y1,1);                                                   % Return ‘bar’ Handle
for k1 = 1:size(y1,2)
    ctr(k1,:) = bsxfun(@plus, hBar(1).XData, hBar(k1).XOffset');    % Note: ‘XOffset’ Is An Undocumented Feature, This Selects The ‘bar’ Centres
    ydt(k1,:) = hBar(k1).YData;                                     % Individual Bar Heights
    text(ctr(k1,:), ydt(k1,:), sprintfc('%.1f', ydt(k1,:)), 'HorizontalAlignment','center', 'VerticalAlignment','bottom', 'FontSize',8, 'Color','b')
end

the sprintfc function is undocumented. It is essentially the same as sprintf, and augmented to produce a cell array of outputs. This makes it very efficient in situations such as this, where the result is a cell array.
