A Colormap instance or registered colormap name. cmap is only used if c is an array of floats. vmin and vmax are used in conjunction with the default norm to map the color array c to the colormap cmap. If None, the respective min and max of the color array is used. It is deprecated to use vmin/vmax when norm is given.

- import numpy as np.
- import matplotlib.pyplot as plt.
- # Create data.
- N = 60.
- g1 = (0.6 + 0.6 * np.random.rand(N), np.random.rand(N))
- g2 = (0.4+0.3 * np.random.rand(N), 0.5*np.random.rand(N))
- g3 = (0.3*np.random.rand(N),0.3*np.random.rand(N))
- colors = (“red”, “green”, “blue”)
