python - 如何在 matplotlib 散点图中设置/获取符号边缘的脊线？

Question

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。

Answer 1

尝试将颜色指定为edgecolors kwarg to scatter。 (注意复数。)

例如

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, edgecolors=carr)
plt.show()
