我使用 matplotlib 创建一个线框，如下所示：

X=sorted(set(X))
Y=sorted(set(Y))
X,Y=np.meshgrid(X,Y)
fig=plt.figure()
ax=fig.add_subplot(111,projection='3d')
ax.plot_wireframe(X,Y,Z)
plt.show()

代码运行，没有抱怨，但我得到的图片真的很奇怪（对我来说），所以我的问题是：

  1. 谁能向我解释为什么接线（可以这么说）是这样安排的？
  2. 我如何决定“如何”连接我的数据（我为什么需要？我期待这个函数将连接每个网格坐标的 Z 值）。
  3. 原来的 X、Y 和 Z 的长度怎么可能是 165，但在执行我的网格网格 X 和 Y 之后的长度是 11（11*11 = 121，缺少 44 个值？）

在此处输入图像描述

您需要重塑Z数组：

XX, YY = meshgrid(X, Y)
ZZ = reshape(Z, XX.shape)
ax.plot_wireframe(XX, YY, ZZ)
