SumOver within WindowSum

You can’t achieve your expected results by filtering on {order_time}

What you need to do is create a new calculated field like so:

minOver(min({order_time}), [{order_time}])

And then use the calculate field within your visual.

This pushes Quicksight to first calculate the window sum, and then apply the filtering for the visual after the sum is calculated.
