Hi there,

I'm not sure how best to go about making a 2D plot of my 3D data. I have calculated FFT of samples at points in the x,y and z axes but I would like to use surf() to plot this information as a 2D surface plot in spherical coordinates theta and phi, how best can I go about this??

Many thanks in advance Bran

Maybe slice() is what you are looking for?

Hey jose, so sorry to be bothering you again, but I am trying to indeed use the slice function for my data as it seems to be the only way to display volume information; I have x = [-7:1:9] y = [-7:1:9] z = [-7:1:9]

v = FFT and I wish to take several slices across the z acces ie; zslice = [0, 5, 9]

but the command slice(x,y,z,v,xslice,yslice,zslice)

is throwing up several errors any idea what might be wrong??

Many thanks :)
