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()
