Text annotations in 3D

Demonstrates the placement of text annotations on a 3D plot.

Functionality shown:

  • Using the text function with three types of ‘zdir’ values: None, an axis name (ex. ‘x’), or a direction tuple (ex. (1, 1, 0)).
  • Using the text function with the color keyword.
  • Using the text2D function to place text on a fixed position on the ax object.

# Demo 1: zdir

for zdir, x, y, z in zip(zdirs, xs, ys, zs):
    label = '(%d, %d, %d), dir=%s' % (x, y, z, zdir)
    ax.text(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.
ax.text2D(0.05, 0.95, "2D Text", transform=ax.transAxes)

# Tweaking display region and labels
ax.set_xlim(0, 10)
ax.set_ylim(0, 10)
ax.set_zlim(0, 10)
ax.set_xlabel('X axis')
ax.set_ylabel('Y axis')
ax.set_zlabel('Z axis')
