python 3D 文字添加功实现

Text

• Axes3D.``text(x, y, z, s, zdir=None, **kwargs)

    text的内容其实也很繁杂，需要用一篇内容去探讨，在三维中很重要的一点是要学会二维、三维文字的添加。

from mpl_toolkits.mplot3d import Axes3D  # noqa: F401 unused importimport matplotlib.pyplot as pltfig = plt.figure()
ax = a(projection='3d')# Demo 1: zdir
zdirs = (None, 'x', 'y', 'z', (1, 1, 0), (1, 1, 1))
xs = (1, 4, 4, 9, 4, 1)
ys = (2, 5, 8, 10, 1, 2)
zs = (10, 3, 8, 9, 1, 8)for zdir, x, y, z in zip(zdirs, xs, ys, zs):label = '(%d, %d, %d), dir=%s' % (x, y, z, (x, y, z, label, zdir)# Demo 2: color
ax.text(9, 0, 0, "red", color='red')# Demo 3: text2D
# Placement 0, 0 would be the bottom left, 1, 1 would be the top right.
