我尝试了以下方法:
import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D
carr = np.array([[0,0,0,1],[0,0,1,1],[0,1,0,1]]) # RGBA color array
ax = plt.axes(projection='3d')
h = ax.scatter([1,2,3],[1,2,3],[1,2,3], c=carr)
h.set_edgecolor(carr) ## also tried h.set_edgecolor('none')
plt.draw()
但标记边缘颜色保持黑色。
