Text annotations in 3D#
Demonstrates the placement of text annotations on a 3D plot.
Functionality shown:
Using the
textfunction with three types ofzdir values: None,an axis name (ex. 'x'), or a direction tuple (ex. (1, 1, 0)).Using the
textfunction with the color keyword.Using the
text2Dfunction to place text on a fixed position on the axobject.
