3D grouped bar-plots from 3D matrix

I'm looking for a way to plot a 3D matrix (3x2x2) as a grouped 3D bar plot where each group has two different bars (according to the third dimension of the matrix). Please see the scratch below as a reference. Thanks

maybe this ?

hello again

based on the comment / link above, this is what I can offer today

%generate somme dummy data
groups_x = 3;
rows_y = 2;
data = 2;
Y = rand(groups_x,rows_y,data);

% plot 
figure(1); 
hold on;

% define x spacing
x_spacing = 2;

% generate ticks / ticklabels
x_vector_ticks = (1:x_spacing:groups_x*x_spacing);  
for ci = 1:length(x_vector_ticks)
    XtickLabel{ci}  = ['Group#' num2str(ci)];
end

y_vector_ticks = (1:rows_y);  
for ci = 1:length(y_vector_ticks)
    YtickLabel{ci}  = ['Param#' num2str(ci)];
end

% main loop
for ci =1:groups_x
    xval = 1+(ci-1)*x_spacing; 
    zval = squeeze(Y(ci,:,:)); 
    h = bar3(zval,'grouped');
    Xdat = get(h,'Xdata');
    for ii=1:length(Xdat)
        Xdat{ii}=Xdat{ii}+(xval-1)*ones(size(Xdat{ii}));
        set(h(ii),'XData',Xdat{ii});
    end
end

% set ticks / ticklabels
xticks(x_vector_ticks);
xticklabels(XtickLabel);
yticks(y_vector_ticks);
yticklabels(YtickLabel);

xlim([0 groups_x*x_spacing+1 ]);
view(15,20);
title('Grouped Style')

Thanks a lot for the valid support. It works perfectly!

my pleasure !

You could probably adjust the DataAspectRatio to make the bars square at their base.
