[yt-users] 1D matter power spectrum

[gso at physics.ucsd.edu]

For each of the random point generated, I want to limit their position to
be on either the x, y or z direction instead of on a sphere, so I can
compare them with the 1D power spectrum.

For example if I want to compare with the 1D powerspectrum along x, I want
phi = 0, theta= pi/2
if I want to compare to z, then
phi = *, theta = pi/2

is this ability already in YT or can it be added easily?
