Matlab 3D probabilty histogram by 2D array

I have 2D data structed by 64X100000 size.

64(rows) represent "phase(-31:1:32)" and 100000(column) represent "voltage" about the range of (-0.4~0.4).

I want to watch probabilty based histogram(pdf) of this data in 64 time instances.

<----- like this pic.

how can i make 3D plot that shows the changes of voltage histogram through 64 phase?

Please help me.......

It looks like that figure might have been created using the spectrogram function.

See this example.

fs = 10e3;
t = 0:1/fs:2;
x1 = vco(sawtooth(2*pi*t,0.5),[0.1 0.4]*fs,fs);

spectrogram(x1,kaiser(256,5),220,512,fs,'yaxis')
view(-45,65)
