How to switch Default Summation off in Power BI

Hi Roisin 

Most visuals require the value fields to be aggregated. For numeric fields, it usually takes Sum by default and adds "Sum of" to the name. You can rename it easily by right clicking on the field and select Rename for this visual. 

For the visuals that support unaggregated fields (Table, Multi-row Card), you can select "Don't summarize" option to show unaggregated values and it will remove "Sum of" from the name.

Thank-you so much! this did the trick to rename it, as the option of 'dont summarize' is not in any dropdown.
