Is it possible to create a Report for the Dashboard that shows the sum of Unopened Emails? Instead of Sum of Sent.

I am trying to create a chart for the Dashboard via the Report Builder (but if there is another way, I am open to that as well) that uses the MDA data for "Email Logs" to show the amount of Emails "Opened" vs "Unopened". Is this possible?



Currently, we have a report set up to Show Me: "Sum of Sent", "Sum of Click Count", and "Sum of Opened". 



The issue with this report is that it basically double counts the emails that were sent and opened and makes the total amount of email logs (Sent, Clicked, and Opened) appear greater than actual. Rather than have the Sent, I think it would show more value to compare Opened vs Unopened. Especially using the 'stacked column' chart option.
