I have two groups created in my Report.

1) ticket origin (email, phone, self-service,Skype and walk-in)
2) Create Date grouped by Month

I inserted a chart with this group data and it is displaying the data that I want. However, I can't figure out how to have a gap between the months. The bars are all equally spaced regardless and it makes it difficult to determine where one month stops and the next one begins. Is there a way to group the 5 bars for Origin together for each month and have a space between each month?
