How to add last year's values to a waterfall graph? (YoY comparison)
I created a waterafall that shows the flow from opportunities to sales for 2019 and I would like to compare it to the year before. In my data, I have the 2019, 2018 and the difference between these 2 years, which I would like to add at the top or the bottom of the 2019 bar. Any experience/ideas on how to add this comparison?
