'Chart' object has no attribute 'configure_facet_cell'
As per the comments this was created on an early version of the software and is no longer reproducible on current Altair versions.
I am using Altair package when I use following objects I have following error message. 
AttributeError: 'Chart' object has no attribute 'configure_facet_cell'
In order to use attribute above, what should I install or add?
Thank you in advance.
