Having a thorough understanding of DAX will allow you to develop visualisations and present data in any way you want. No longer are you constrained to using the standard formula that comes with Excel. You no more have to work out complex time analysis functions that should be straightforward. Formulas such as Year to Date or Quarter to Date or even working out how much you''ve earned this financial year.
