| outValues | The merged samples for the specified hierarchy item, returned as a list of doubles. This list is resized if necessary. | 
Retrieves the merged samples for a specific hierarchy item. Merged samples are returned as a list of doubles through the outValues param.
        When HierarchyFrameDataView uses ViewMode.MergeSamplesWithTheSameName mode, samples with the same name, and at the same hierarchy level, are merged and represented by a single item. In this case, GetItemColumnData represents an aggregated value.
Use GetItemMergedSamplesColumnDataAsDoubles to obtain double values for individual samples in a merged hierarchy.
The resulting list of doubles is written to outValues. This list is resized if necessary.
