With error bands in Power BI, the implementation of adding vertical reference bands is quite easy. The key lies in two DAX formulas in order to obtain multiples reference bands that could be either adjacent or non-adjacent to each other. Many thanks to Parvinder Chana for his approach on highlighting data points based on slicer selection. Also, many thanks to the FRED charts for the inspiration.
