Also, our Line chart nicely visualizes trends for easier comparison, while Card visuals in the upper left corner show Sales Amount for the selected period and difference between two periods which we are comparing. SAMEPERIODLASTYEAR Returns a table that contains a column of dates shifted one year back in time from the dates in the specified dates column, in the current context. so for a specific date.. The last chart sets the prior year on the zero axis, showing that while sales underperformed at first, they continued improving and eventually ended the year above target. The first step is to create a base measure to calculate Sales Amount: I will straight away create another measure, which will calculate same figures, but shifting one month back: There are multiple different ways to calculate this measure, but I prefer using DATEADD() function since it gives me more flexibility with shifting periods (thats an official excuse:)In reality, Im coming from the SQL world, where DATEADD() is one of the most important functions when working with dates).

The previous period will show May 1st to May 30th, but leave out May 31st because the measure goes back by the number of days, not by month.Can this measure be modified to show the previous period as a complete month? For example, June 1-June 30th is the current period. This plot remains easy to follow as time goes on and more years make their way into the view. @joshcorti11I think you are over-engineering the problem. I want to create a measure that calculates the difference between the average of the most recent report period attainment track grade and the previous report cycle. Previous period calculation should be number of days in this period minus start of current period. The month to month comparison excel chart will appear in the worksheet.

DateAdd is a function that adds or subtracts a number of days/months/quarters/years from or to a date field. Knowing the current month of a cell in the visualization, the previous month is the maximum month number available in the filter context provided by ALLSELECTED excluding the current and following months. Geschftsfhrer: Mel Stephenson, Kontaktaufnahme: markus@interworks.eu Cheers As per the requirement, dashboard should contain a Parameter where user can select a Start period and end Period . ALLSELECTED ( [] [, [, [, ] ] ] ). Which design tells that story the best? ParallelPeriod and DateAdd can go more than one interval back and forward, while SamePeriodLastYear only goes one year back.

Sales = SUM(FactResellerSales[SalesAmount]) instead of Sales = SUM(FactInternetSales[SalesAmount]), I might have used the wrong measure name but the tale name looks alright to me . Also in this case, if you are using Excel 2010/2013 or Analysis Services Tabular 2012/2014, you cannot use the variables. file size: 100 MB. Hi Everyone,I am currently using the measure below to compare the current period and the previous period, but since the measure is going back by number of days I am running into a problem. DateAdd and SamePeriodLastYear both work based on the DYNAMIC period in the filter context, ParallelPeriod is working STATICALLY based on the interval selected in the parameter. The approach shown in this article is data-driven and ignores the current calendar date, which might result more reliable if you might have delays in populating data for your model. Focusing on only two points in time can skew perceptions by ignoring broader trends or using a poorly chosen baseline. Just recently, Ive come across a question on the LinkedIn platform, if its possible to create the following visualization in Power BI: Since one of the common business requests is to perform different comparisons between various time periods, I would say that Power BI has a lot to offer in this regard.

To begin with, it is important to make the current year stand out with a different color and bolder line (inspired by an auto accidents viz by Andy Cotgreave). I have illustrated the issue that is still persisting below. Create a measure with the following dax. That works perfectly. Now, when I choose dates between November 17th and December 17th, I can see how my numbers correlate between themselves: As you may notice, our formulas work well as intended, we see that Sales Amt PM for December 17th, matches Sales Amt for November 17th. Repeat steps 1-7 to create theEnd Date parameter. @joshcorti11there is no concept of almost perfectly, it is working or not, you have to use calculation group, maybe with 4 calculation items: The top 3 are self-explanatory, and in the 4th one, use the range from date slicer and then do the comparison for the same period as you are doing now. An alternative layout known as a cycle plot solves this problem.
