Maybe I misread your question but if you want to put the customers into purchase buckets depending on count of customers during a particular date range, then all you need to do is add the date filter to context. See example screenshot below. The first screenshot shows the summary and the second shows the details.
Hope this helps.

Thank For the replay Bharat. This link calculation based on the datediff of month.
But in my case i have calculate based countd(Orderid). Please let me is there any other way to achieve this.
In the above case, we have 1 to 7 Purchase Summary.
1. The client want to see 2 & 4 th purchase in Purchase bucket.
2. For 1 Purchase Bucket, The # of Customers Count would be 9 (Aggregation of below purchase bucket)
