Install: Matplotlib v 1.4.3, Python 2.7.1 with pip.

Traceback (most recent call last): File "realtime.py", line 10, in <module> from matplotlib.widgets import Slider, Button, RadioButtons, TextBox ImportError: cannot import name TextBox

I can see TextBox in the documentation listed the same as Button, Slider but it doesn't work. Other widgets do work.
