I'm trying to get the count of all the jira issues in my project, based on labels. As you can see below, I'm able to achieve it by using "Jira Chart" macro, you'll see the issue count based on labels.

Now, the problem is sometimes team members don't add labels for their Jira issues, and those are NOT getting counted in this result received from "Jira Chart" macro. You can see the total value doesn't actually add up, for each assignee.
For eg: take the first row, assignee has actually 65 Jira issues with him but he used Labels in only 12 Jira issues and 53 of his Jira issues basically has no labels. How do i get that 53 displayed as something like "none" column in this result?
