Matplotlib deprecation of Axis `set_smart_bounds`

[decmur]

In Matplotlib method set_smart_bounds is deprecated and throws the following error when performing analysis

AttributeError: 'XAxis' object has no attribute 'set_smart_bounds'

Seems that this capability was deprecated in matplotlib==3.2 but throws the error with older versions as well.
