Hi there,
I have a table, each column represents the amplitude of frequency on different flow rates of a centrifugal pump, like this.
i plot spectrum in 2d but looks like this:
I want to plot this spectra on different flow rates in 3D, and should looks like this:
How can i do this?
Thanks!

What does your code look like that produces the 2D plot?
If the entire matrix is the 1st and only input to waterfall(), it should produce a 3D waterfall plot.
waterfall(Z) creates a waterfall plot, and uses the column and row indices of the elements in Z as the x- and y-coordinates.
Note that neither of the plots in your question show a waterfall plot. As darova mentioned in the comments under your quesiton, perhaps you're looking for the gool ol' fashion plot3(X,Y,Z).
[x,y] = meshgrid(1:size(T,2), 1:size(T,1)); % T is your table
z = T{:,:};
plot3(x,y,z)
grid on

Hello Adam,
in the Bizau's plot 3D he obtain different colour for each graphs at different flow rates.
How it is possible to have the graduated colour on all the graphs?
Thank you
