Getting Data only for last year MS BI DESKTOP

Hi,

I'm very new in MS BI. I'm trying to see what is the most effecient way of returning only 365 days of data into my Bar Chart I have created. Is there a way to create a New Column as a calculation that I can drop it as a part of the Chart? So, basically, the chart woiuld be based on all the rows for the last 365 days.

Thanks so much for your time.
