Bar3 plot increase bar thickness

I am trying to plot the stacked bar3 plot. How to increases the thickness of the bars? All the bars look flat. I need something like this with thick bars stacked next to each other.

What I am getting is:

Below is the code and I have also attached the dependency files. Please let me know a solution.

clc; close all; clear;
 
% Load mat file
load ('TextureData.mat');

% Plot 3D graph
hFig = figure;
for k = 1:length(imbincountstack)
    crackclass = imbincountstack{k};
    if (size(crackclass,1) == 1)
        crackclassnew(1,:) = crackclass(1,:);
        crackclassnew(2,:) = [crackclass(1,1)+1, zeros(1,length(crackclass(1, 2:end)))];
    else
        crackclassnew = crackclass;
    end

    z = crackclassnew(:,2:end);
    h = bar3(crackclassnew(:, 1), crackclassnew(:, 2:end),width,'stacked');   
    hold on;
   for j=1:length(h)
      set(h(j),'xdata',get(h(j),'xdata')+k-1);
      set(h(j),'FaceAlpha',texturefeature_inpstruct.alpha)
   end

   % If crackclass has only one row then pad with zero and hide zero
   % bar graph
   if (size(crackclass,1) == 1)
       for i = 1:numel(h)
          index = logical(kron(z(:, i) == 0, ones(6, 1)));
          zData = get(h(i), 'ZData');
          zData(index, :) = nan;
          set(h(i), 'ZData', zData);
       end
   end

   crackclassnew = [];
end

set(gca, 'PlotBoxAspectRatioMode','auto')
set(gca, 'XTickLabel',class_string, 'XTick', 1:numel(class_string), 'FontSize', 20, 'LineWidth', 3) %, ...
ylabel ('Image Resolution (kilo pixels)', 'FontSize', 20)
zlabel ('Number of Images', 'FontSize', 20)
if (texturefeature_inpstruct.lowTextureonTop == 1)
    legend ('High Texture','Low Texture','Location','NorthEast');
else
    legend ('Low Texture','High Texture','Location','NorthEast');
end
hold off
axis tight;

hYLabel = get(gca,'YLabel');
set(hYLabel,'rotation',-18,'VerticalAlignment','middle')

% resize the figure window
set(hFig, 'units','normalized','outerposition',[0 0 1 1])

If you read Mike's blog post (where your desired image comes from), you'll notice he wrote his own function for creating a 3D stacked bar plot.

For your bar3 plot, there is a scale issue. Your Y-values cover such a large range that the width in Y is getting compressed so that everything fits. The most they can be here is the width of the distance between two values on the Y axis, 1. For fatter bars, you either need to bin your data into groups, change the aspect ratio so the plot extends much further in the Y direction, or plot a subset of the data that does not have such a large range of Y values.
