Activating inactive relationships the smart way

Hi, today I want to talk about inactive relationships. Those relationships with the dashed line that unless you invoque them with USERELATIONSHIP they do nothing.

Somebody was trying to build a matrix and wanted to have the values without decimals but the totals with decimals. In other words the goal was defining different formats for values and tot...

Normalizing conditional formatting bars

Ok, this is one of those things that I might not do in production unless I have the CEO shouting on my ear "I want the bars of the matrix to be smaller so I can read the numbers, and no, you may not use a custom visual for that!". I know that might be[...]

Creating well-formatted measures based on a calculation group

Calculation Groups biggest contribution is to help us reduce the number of measures that we have to create and manage. However, sometimes, me might want measures again...

Creating a dynamic KPI card

I'm always keep an eye open for potential new members of the Barcelona Power BI User Group. When I see a potential candidate I try to connect and get to know him/her. Today I was surprised that one of these unsuspected new members told me he was already using my script for Time Intelligence (yay!)[....
