Hi Tymoteusz,
I think this does what you want (see attached).
I'm not sure about 3D though.

Hi!
Can anyone help me to achive this?
I'd like to plot rgb spectrum with matplotlib.
For example let the x axis be green element, and for example... let the y
axis be red element.
Eventually i'd like to plot 3D figure with all of three elements RGB.
Regards,
T.
import matplotlib.pyplot as plt
import numpy as np
a = np.outer(np.arange(0,256), np.ones(256,dtype=np.uint8))
rgb = np.zeros((256,256,3), dtype=np.uint8)
rgb[:,:,0] = a
rgb[:,:,1] = a.T
plt.imshow(rgb, origin='lower', interpolation='nearest')
plt.show()--
