Hi,
How can i have a plot similar to this in matlab, I have Frequency data from 0-25 kHz (size 300*1), and amplidute data of size=300*200, Where 200 is my number of cycles.
Purpose of this graph is to understand how the amplidute of frequency increases with cycle. The same i'm not able to inference from the surface plot.
Thanks in advance !!

You can do something like this
c = 1:200;
f = 1:300; % replace with your freq
a = filter2(ones(11),rand(300,200)); % replace with your amplitude data
surf(c,f,a,'EdgeColor','none');
xlabel('Cycle');
ylabel('Frequency');
zlabel('Amplitude');
view(-60,60);
