This has been asked before but I haven't seen an answer. How can I create a burn-up chart that shows scope reductions?
For example, I have a property called "Added to scope on" and one called "Removed from scope on". For every date on the x axis, I would want to show the sum of planning estimates for cards that were in scope on that date. At a later date, one such card could be removed from scope. I would want to show that dip on the chart.
With the standard cumulative chart, moving a card on a given date out of scope moves the whole line down, rather than showing a reduction on that date.
