how to plot a 2D graph on top of a 3D surf

i have a PSD spectrogram and want to plot on top of that a time series graph. In the link is what i want to achieve:<https://docs.google.com/file/d/0B61s6H8F7eyNVXFCNFVseFFaUUE/edit?usp=sharing>

Any idea?

Such a plot is not going to happen automagically. I suggest you look into patch() and arm yourself with some patience. surf() could also work, depending on the kind of data you have.

i already created the spectrogram, but i want to put also the timeseries. the spectrogram is the fft of the time series. now i want to put them together and try to figure out the hole thing.

I can't see the link, but if you have a surf, you can simply issue the commands:

hold on

plot3(x,y,z,colour)

To plot a line arbitrarily over/around/behind your surf. Set x, y or z = to a constant, and you can plot a line on an arbitrary plane.

i tried but i didn't sucede.

@effess: Please post the code you have created so far an explain "did not succeed" with all necessary details.

so this is my code, i built the surf and when i plot the graph i get 'Error using plot3 Vectors must be the same lengths.'

figure;surf(tw(172,1:end),Fw,10*log10(afftp),'edgecolor','none'); 
axis tight; 
view(0,90);
xlabel('Time (Seconds)'); 
ylabel('Hz');
hold on ; 
plot3(tw(172,1:end),xhb(172,1:end),1)
