Hi @JPickham,
If you have 9 lists, then it’s not possible to tell HubSpot to display the count of each list as a separate bar. The report builder simply does not work that way.
Instead, you would approach this slightly differently. I assume that each of your lists is based on the value of a date property of those contacts, e.g. “Became a lead date”. In custom contact report, you can show the Count of contacts by Became a lead date and select a monthly frequency. HubSpot will then automatically group contacts by month into bars as shown in your screenshot.
If you provide more details about how your lists are created, I can share more context on how to create such a report. With 9 lists, it’s not possible.
Best regards!
