1. Data label (numeric) - Select the aggregation in Number formatting -> Data_label_column_name Aggregation Type option. It provides a dropdown to select the aggregation for numeric values in data labels.

   1. $Sum= Σd$
   2. $Average= Σdl/n$
   3. Parent bar data label of weighted average type is the sum of its every child bar's product of duration and data label value, divided by the sum of all its child bars duration.$Weighted Average = (Σ(d x dl))/Σd$

Where n is number of child bars, d is the duration of child bar, dl is the data label value of the child bar.
