Dynamic Pie Chart Percentage

If someone can pinpoint my error 

You are using a pie chart.

In the vast majority of cases a pie chart is the wrong visual type.  It is only applicable if no filters are applied, or if the data in that pie chart truly represents 100% of the data subject.

Consider trying out other chart types.

Hi zohra69 ,

As lbendlin  said, pie charts work best when showing a limited number of categories to compare parts of a whole.
But you can try modifying the expression, something like

VAR TotalCost =
CALCULATE(
SUM('Fact_Astro_PU_ALL_ICB'[Actual Cost per 1000 ASTRO PU]),
ALLSELECTED('DatesCalendar'),
ALLSELECTED('DIM_Region')
)

The ALLSELECTED function removes contextual filters from columns and rows in the current query, while retaining any other contextual filters or explicit filters. For detailed information, please refer to the document: ALLSELECTED function (DAX) - DAX | Microsoft Learn.

If your Current Period does not refer to this, please clarify in a follow-up reply.

Best Regards,

Clara Gong
