# This example demonstrates mplot3d's offset text display.

# As one rotates the 3D figure, the offsets should remain oriented

# same way as the axis label, and should also be located "away"

# from the center of the plot.

# This demo triggers the display of the offset text for the x and

# y axis by adding 1e5 to X and Y. Anything less would not

# automatically trigger it.
