The new Waterfall chart is Qlik Sense is handy, you however can only define measures.
I would like to create a waterfall chart as per the next screenshot where it shows in blue for weeks where the qty movement was positive and red when the week's qty movement was negatively (cumulatively)
I've the same problem and I beleve that QS doesn't support this functionality. I want to create a waterfall chart with the dimension MONTH and measures START_QUANTITY and USED (that will subtracted from START_QUANTITY.
Something like this
When I use the free QS Extension "AnyChart" it works
