Level up UX by leveraging advanced DAX

You’ve faced this – you gathered precise business requirements, designed efficient data ingestion into a carefully crafted star-schema, authored state of art DAX and beautiful visuals – all to receive a ‘meeeh’ from the client because they can’t properly see the data label on the highest column in the column chart. Or because they picked a product from the product slicer only to face a completely blank report page and find out that this product isn’t actually sold in the currently selected country.

I’ve been there too. And while putting a background in the data label solved the first problem mentioned at first (at least partly), I realized that this is not the ultimate solution we want to aim for. Neither was enabling a bi-directional relationship to fix the second problem.

Throughout my Power BI journey I’ve faced a number of these issues, all of them having two traits in common: they heavily hindered User Experience and could be solved by a bit of smart DAX. During the session I’ll share these challenges and solutions to help you tie up the last loose ends in your report. And impress your client – be the client external or your boss.

After the session you will be able to:

  • Improve the scaling of charts
  • Create visuals with custom labels using different approaches
  • Limit the number of options in slicers to only those available in current context without resorting to bi-directional relationships

Before you join this session it would be great if you have a good understanding of DAX concepts and dimensional modelling in Power BI.
