From the values in `cols` in `self.xtra` .?, label_from_df

(Javier) #1

Folks, this description is a bit cryptic, can somebody explain what label_from_df does, thank u :wink:

what is self.xtra?

label_from_df ( cols : IntsOrStrs = 1 , kwargs )

Label self.items from the values in cols in self.xtra .

Warning: This method only works with data objects created with either from_csv or from_df methods.
