Plotting in 3D: Probability Density Plots Over Time

There are many ways of plotting in 3D in matlab. I have got some reasonable results using the following method. This post is to enquire how other people might tackle the common problem of representing PDFs moving over time.

N = 1E4; %number of experiments, eg Monte Carlo
T = 3E3; %number of timestamps
wHat= randn(T,N); %at each point in time you get a distribution of probabilities. 
ksData = NaN(T,N);
binVals = linspace(0,1, N); %assign the probabilities to one of these buckets
    for t = 1: T
        ksData(t,:) = ksdensity(wHat(t,:), binVals);
    end
    surf(1:T, binVals, ksData');
    colormap jet;
    shading interp;
    colorbar;
    view(-37.50, 30);
    set(gca, 'XLIM', [0 T]);
    set(gcf, 'color', 'white');
    grid on;

This seems to give a decent visual representation of whats going on.

However, I am aware that I haven't smoothed across time, only across experiments.
