I created a system view to display the number of emails sent for a customer support center last week.

I created a "Tag" chart to display the number of emails sent per employee. Here's the chart on the backend:


The problem is that the number of records in the view itself, independent of the chart, there are, 5 emails for example for a certain employee, but the chart shows they did 10. It doubles the amount for every employee, and I'm not sure what I did wrong with the chart.
