I have over 2000 records in my CSV file that I want to use to keep track of how many times we order a product. And each record has its own product ID, So a product could be ordered multiple times, so I want to know if there is a way to figure out how many products have been order where fields that have the same product ID are only counted 1 time. And also how to filter this chart by year. Thank you for your help in advance. ---

Hi, Unique count aggregation on any of the fields in y-axis should be able to give you this on charts. And then you can filter by the year on x-axis. ![24%20PM](https://us1.discourse-cdn.com/elastic/original/3X/a/5/a593ebf85fbe6b4217e7ca7e1a5d9069513572d7.png) Thanks, Bhavya ---
