AlloViz.AlloViz.Elements.Edges._check_is_chained_assignment_possible

Edges._check_is_chained_assignment_possible() → bool

Check if we are a view, have a cacher, and are of mixed type. If so, then force a setitem_copy check.

Should be called just near setting a value

Will return a boolean if it we are a view and are cached, but a single-dtype meaning that the cacher should be updated following setting.
