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.
