How do you create a cumulative sales graph in PowerBI

Question

The bar and line charts in Power BI allow you to graph total sales by month. Example Jan Sales $100 Feb Sales $200 Mar Sales $150

I am looking for a way to graph those same numbers but show a cumulative sales total to show total revenue for the year. Essentially, I would like the total for the current bar added to the sum of all bars to the left of it. Example from above would look like this: Jan Sales $100 Feb Sales $100+$200= $300 Mar Sales $300+$150= $450

This would allow you to see total sales volume over the year. Any ideas on how to make this happen?

The easiest and clearest visual to achieve this would be the "Waterfall chart", which would look like this:
