I think this is misleading in three ways: first, because some collections also know how to change the dataLim; second, because there are other Artist subclasses; and third because the general advice should be, 'Use add_artist only for artists for which there is no dedicated "add" method; and if necessary, use a method such as `update_datalim` or `update_datalim_numerix` to manually update the `dataLim` if the artist is to be included in autoscaling.'
