使用matplotlib显示六边形网格

import matplotlib.pyplot as plt
import matplotlib.patches as patches

fig, ax = plt.subplots()

side_length = 1.0  # 六边形边长
center_x = 0.0  # 六边形中心点x坐标
center_y = 0.0  # 六边形中心点y坐标

hexagon = patches.RegularPolygon((center_x, center_y), numVertices=6, radius=side_length/2, orientation=0, facecolor='none', edgecolor='black')
ax.add_patch(hexagon)

ax.set_xlim(-10, 10)  # 设置x轴范围
ax.set_ylim(-10, 10)  # 设置y轴范围
ax.set_aspect('equal')  # 设置坐标轴比例为1:1
ax.axis('off')  # 关闭坐标轴显示

plt.show()
