I have multiple FFT plots and I want to show them together in one plot, something like the attached figure.
To improve readability of the plot created in the @rayryeng answer one may also add white stripes below each line that will block deeper lines (DZ controls stripe width which is set to 10% of the Z-axis span):
ZL = zlim(gca);
DZ = 0.1*(ZL(2)-ZL(1));
for k=1:size(xMat,2);
hPatch(k) = patch( ...
[xMat(:,k); flipud(xMat(:,k)) ], ...
[yMat(:,k); flipud(yMat(:,k)) ], ...
[zMat(:,k); flipud(zMat(:,k))-DZ], ...
'w');
set(hPatch(k), 'EdgeColor','none', 'FaceColor','w', 'FaceAlpha',0.9 );
end
axis tight
