Sum months for Dashboard

Umang Ahluwalia

Hi, I am creating a dashboard for month wise data, what i am struggling with is that if i have rows for multiple months then it is displaying as seperate bars I wanted to merge that amount into one month. Attaching a screenshot below, you can see there are two septembers I wanted to merge or sum that into one, Can any one help please?
