This article shows how to compute a measure that sums the values produced row by row in the visual into the visual total, instead of recomputing the total value in the filter context of the total. Read more

In this article we demonstrate how to use calculation groups to show the behavior of any measure in the last 6 months, starting from a single date selection with a slicer. This can be applied to any number of months. Read more
