Patrick LeBlanc explains a confusing part of KPIs in Power BI:
Now, take a look at the KPI visual. What happened? First, you should notice a trend line on the KPI that depicts Sales Amount for each month. This is cool and a great feature of the visual, but wait. Why doesn’t the Indicator value and the goal match the values in the Card? Now I see the confusion.
I appreciate that Patrick put in several embedded reports to show us exactly what’s going on.
