List<LabelInfo> LabelCollection.CreateLabelsAtXCoordinate(Quantity param1)

Creates label(s) on the dataset at a specified X coordinate. This API may return multiple `LabelInfo` references in case the corresponding dataset has more than one Y-value for the given X-value (for eg. Spiral graphs). 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.
