When the input series are displayed, you can specify the Input type and assign Weight to each input.
For individual input series
Go to Input type, select an option from the dropdown: Raw data (in levels), % Change (percent change) or % Change, YoY (year-over-year percent change).
Go to Weight, %, specify the percent weight for each input. The weight is to be non-negative. The tool automatically rebalances all weights to a total of 100% during calculation.
For bulk changes to all input series or a subset of series
Select the checkboxes for the series
Go to Edit, and update Input type and Weight, %.
To apply same weights to all input series
Click the vertical ellipsis (⋮)
Select the option Equalize weights
To normalize weights to a total of 100%
Click the vertical ellipsis (⋮)
Select the option Normalize weights
Note: the tool automatically rebalances all weights to a total of 100% during calculation. You only need to normalize them if you choose to do so.
