How do you make a stacked cluster chart?
I am trying to make a cluster chart categorized by different emails sent out to customers (Let us call them Email 1, 2, and 3) and have each email type stacked based on the response (opened and clicked). Is it possible to have your chart be both clustered and stacked? The x-axis is labeled by the day of the week, and I would further group it by the email (1, 2, and 3) on each day.
Thank you in advance for the help!
