Hi hope this gives you ideas on how to get the result you are looking, I'll show you one example to display New Customers per month and Customers that place an order on or after 365 days (Resurrected customers) per month.
For this example, I'm using SQL Server and a version of Superstore dataset.
We need to calculate the difference in days between orders for the Resurrected customer (Customer with a year or more that a year with no orders)
To do this I will generate another column that has the previous order date per each Order ID, also match all this information per customer, having this structure it will be a lot easier to analyze.
I followed Bronson Shonk article Tableau Doctor: 1 Column, 2 Dates? Use Custom SQL | Tableau Software to create the customs queries.
When I establish the connection to my server on the data source page create the first Custom SQL
--Custom Query 1 to get the order number with DENSE_RANK() function
Then I created another Custom SQL, this second custom SQL is to generate the previous order date value. Also, we generated a previous order number for a LEFT JOIN.
Perform a LEFT JOIN between these 2 Custom SQL
The data look like this
Customer first order
New Customer Condition
Days Between orders
Raw data view
Visualizing the values by month
Attached .twbx file for reference
Let me know if this helps!
