List<LabelInfo> LabelCollection.CreateLabelsAtYCoordinate(Quantity param1)

Creates label(s) on the dataset at a specified Y coordinate. This API may return multiple `LabelInfo` references in case the corresponding dataset has more than one X-value for a given Y-value. Each `LabelInfo` reference corresponds to the multiple anchor positions thus obtained. An ArgumentException will be thrown when creating a Label at a location already assigned to another Label.
