I would like to plot several histograms in 3D using Matlab like in the below figure. Does anyone have any suggestions?

Check out bar3

Thanks for your answer, Joshi. I try to use bar3, but the output is not appropriate with what I want. Perhaps you have code to plot a figure like I asked previously.

Thanks for your answer, Cameron. You suggest to check out a solution using fill3. However, the way to plot several histograms is different from fill3 command, since syntax for bar3, histogram2, hist3 is not like fill3 which uses 3 vectors, i.e., X, Y, and Z in each coordinate axis.

I could have sworn I'd posted an answer to a similar problem, but maybe I'm dreaming. Here's one way of doing it with bar3().

% say you have some data

% i'm just going to use channel histograms from an image

inpict = imread('peppers.png');

nbins = 64;

counts = zeros(nbins,3);

for c = 1:3

[counts(:,c),~] = imhist(inpict(:,:,c),nbins);

end

% plot them using bar3()

xoffset = [0 10 20];

alpha = 0.5;

hb = bar3(counts);

for k = 1:numel(hb)

hb(k).XData(:) = xoffset(k);

hb(k).FaceAlpha = alpha;

hb(k).LineStyle = 'none';

end

xticks(xoffset)

colormap(hsv(numel(hb))) % or pick whatever map you want

% adjust dataaspect to force spacing on x

xscalefactor = 2; % adjust me

yl = ylim; % store for later

hax = gca;

hax.DataAspectRatio(1) = hax.DataAspectRatio(1)/xscalefactor;

% clean up view

ylim(yl)

xlim(xoffset([1 end]))

view(-55,20)

While bar3 allows a Y parameter, that seems to really only be useful for setting the position of data groups, not series. Given that, I don't see a simple way to do this without a bunch of direct manipulation of the individual surf objects.
