python - 我的散点图只显示数据的一部分

Question

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))

data = (g1, g2, g3)
colors = ("red", "green", "blue")
groups = ("coffee", "tea", "water")

fig = plt.figure()
ax = fig.add_subplot(1, 1, 1)

for data, color, group in zip(data, colors, groups):
    x, y = data
ax.scatter(x, y, alpha=0.8, c=color, edgecolors='none', s=30, label=group)

plt.title('Matplot scatter plot')
plt.legend(loc=2)
plt.show()

创建 pyplot 图之前的任何代码都不能更改。似乎 for 循环无法正常工作。我不确定问题是什么。没有任何错误。
