Hi All,

I am looking at the various way of plotting 3D graph. I had the below code to read an audio wav file and i understand that to use coneplot i must have velocity vector. I had read the help manual but i still dont quite understand it. Kindly check if I am able to use cone plot to plot the frequency spectrum of the data or psd of the audio signal? Appreciate for your help or example of how to do it. Rgds & Tks

[filename, pathname] = uigetfile('*.*', 'Pick any file');
[y, fs, nbits] = wavread(filename);
