Thank you for the good bug report. You did find a bug in the axis ticker. And thanks to the easy to follow example it was easy to fix. Please try version 2.1.3 on pypi or from here. It should work now.

You are right again. Thank you! I will make a new release shortly.

2.1.4 fixes the "remove" bug of your example. Please try it.
