Hello,
I am trying to make a vibration spectrum plot using the waterfall command. I want the X axis to be time, Y to be rpm, and Z to be the amplitude of the frequency. I have produced a plot but it does not look similar to my reference. My plot does not show the color gradient for the z axis and it does not have the lines on the floor of the graph like other waterfall plot examples have on Matlabs website.
Nor = [linspace(0,4000,13) 3600 2660 linspace(2646,2646,14) 2660 3200 linspace(3800,0,12)] ;
time = linspace(0,43,43);
BPFO_A = (n/120)*(1-(d/D)*cos(thetaA))*(abs(Nor+Nir));
[X,Y] = meshgrid(time,Nor);
Z1 = meshgrid(BPFO_A,Nor);
z = meshgrid(Nor,BPFO_A);
figure(1)
waterfall(X',Y,Z1')
