Calculate Year to Date Year on Year Growth

[Anonymous]

Hi All,

I'm new to Power BI and just wanted to know how it is possible to create a year to date vs previous year bar chart. My source data is events data over the last few years - one record per event and multiple events per day. I can create a cluster bar chart that gives me a monthly comparison since the beginning of last year but alongside it i would like a chart that shows year to date comparison vs last year (based on the last full month).

Dummy data below as an example - summary by month and year (matrix) which can be plotted as a cluster bar and no additional manipulation to the source data required. The year to date figures will exclude the partial current month.

Month	2018	2019		Period	2018 YTD	2019 YTD
Jan	61	91		Events	441	394
Feb	82	34
Mar	50	24
Apr	1	94
May	58	81
Jun	62	25
Jul	87	41
Aug	40	4
Sep	3	35
Oct	85
Nov	40
Dec	45

Any ideas on how to proceed - do i need to create a separate summary table etc?

And as a separate question given my source data will be udpated every day how do i make both charts dynamic so i will only ever see the current year vs last year without having to hard code the years?

Thank You

Hi @Anonymous ,

we can try to use the following measure to meet your requirement.

ThisYear = 
CALCULATE (
    SUM ( 'Table'[Value] ),
    FILTER ( 'Table', 'Table'[Date].[Year] = YEAR ( TODAY () ) )
)

LastYear = 
CALCULATE (
    SUM ( 'Table'[Value] ),
    FILTER ( 'Table', 'Table'[Date].[Year] = YEAR ( TODAY () ) - 1 )
)

BTW, pbix as attached.
