Multiple bar plots and error bars

Hi,

Could you please help me on how to plot multiple bars (means) and their respective error bars(standard deviations)?

please find example of my data below;

meanA = [1.9000 5.1333 9.6167]

meanB =[2.1069 4.8297 8.8746]

meanC =[1.6632 6.1078 9.9431]

SD_A =[0.1549 0.3983 0.2137]

SD_B =[0.5744 1.0037 0.9494]

SD_C =[0.7757 1.6038 1.5165]

THANKS

Try this:

meanA = [1.9000    5.1333    9.6167];
meanB =[2.1069    4.8297    8.8746];
meanC =[1.6632    6.1078    9.9431];
SD_A =[0.1549    0.3983    0.2137];
SD_B =[0.5744    1.0037    0.9494];
SD_C =[0.7757    1.6038    1.5165];

meanABC = [meanA; meanB; meanC]';
SD_ABC = [SD_A; SD_B; SD_C];

figure
hBar = bar(meanABC, 0.8);                                           % Return ‘bar’ Handle
for k1 = 1:size(meanABC,1)
    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, SD_ABC, '.r')                                    % Plot Error Bars

Hi,

you can use the functions bar and errorbar.

Plot your Mean-Data with bar and your standard deviation with errorbar.
