Having issue with pie chart in dashboard

Hello, iam getting combination of customers in pie chart as slice in selling dashboard.

if there are 6 customers, there are 6 slices for 6 different customers.
if there are more than 6, eg 7, then there are 5 slices for 5 different customers and 2 customers are combined as 1 slice.

if there are more than 6, eg 8, then there are 5 slices for 5 different customers and 3 customers are combined as 1 slice.

The problem is , the pie chart is having 6 slices only. if more than 6 customers are there, it combines.

but i want different slices for different customers irrespective to the number

Please help me to achieve this.

Thanks in advance.
