multiple sum aggregation

[SujPer]

Hello Nicolas,

I hope you are well. I was taking a look through the widget and think its fantastic. I did however have a question around the seeming restriction of the 'value' fields. Am I correct in assuming that it only allows one value field when the aggregation type is 'sum'? If so, is there any recommended workaround for this please?

Thank you,

Yes, the built-in sum aggregator accepts only one value, but in principle you might be able to build a sum operator that sums across multiple values at the PivotTable.js level and then fork this Jupyter integration to include that. It's not something I have any time to work on, but there are no technical obstacles :)
