Hi @scottypotty4x4 ,
I've made a test for your reference:
I assume there is a table
ClearCollect(YourTable,{Mileage:24157},{Mileage:61474},{Mileage:78451},{Mileage:10147},{Mileage:97414});
You could set the pie chart's items property to:
ShowColumns(AddColumns(GroupBy(
AddColumns(
YourTable,
LabelColumn,
If(
Mileage<=15000,"0-15,000",
Mileage<=30000,"15,001 to 30,000",
Mileage<=45000,"30,001 to 45,000",
Mileage<=60000,"45,001 to 60,000",
Mileage<=75000,"60,001 to 75,000",
Mileage<=90000,"75,001 to 90,000",
"90,001 and up"
)
),LabelColumn,NewGroup),Count,CountRows(YourTable)),LabelColumn,Count)

Best Regards,
Bof
