Hi - could someone please share some best practices for setting up waterfall charts?I’m trying to create a bridge: Starting Headcount, New Hires, Terminations, Ending HeadcountQuestion 1: does the formula in Ending Headcount have to be “Starting Headcount + New Hires + Terminations”? It seems like yes if I want to create a Contribution Waterfall Chart. In this scenario I’d have to create an Iterative Calculation and use the “PreviousOf” function for the starting headcount, right? Or is there a better way?Question 2: Is there a way to make the periods that are shown in the chart dynamic based on the page selectors? We’d like our users to be able to select which months to see. For example, if they select June and September, they should see a waterfall with June Starting Headcount, all New Hires and Terminations for June/July/August/September, and then Ending Headcount for September. Is this possible?Question 3: is there a reason I can’t control the Aggregator Settings in the chart? This

Hi there, I haven’t really found something related to this topic, hence this new one. I am fairly new to Pigment and have been working heavily with other planning solutions so far. What I see in every project is the need to easily set up parent-child hierarchies for cost centers, profit centers or products. Those can have many levels (e.g. a 10 level deep cost center hierarchy). In other solutions I would get all node and leaf items from a source system and add the respective parent in a separate hierarchy column (so I need to keep two columns maintained to have a full multi-level hierarchy). What is the equivalent of this in Pigment? Thanks everyone! *Update: my apologies, I was actually referring to parent child hierarchies. Would that change the approach?
