Compute an average for the same day in the past 3 years

{4 Comments}

Assume a simple two column dataset with dates in column A and numbers in column B. The dates in column A are from January 1, 2013 to December 31, 2016 and numbers in column B are for the period January 1, 2013 to December 31, 2015 (there are no numbers for January 1, 2016 to December 31, 2016).

The objective is to "Compute an average for each day of calendar year 2016. The average should be for the occurrence of that day in the previous 3 years". Here's an example:

1. January 1, 2016 was a Friday (the first Friday of 2016) and is in cell A1097
2. In cell B1097, the average should be computed as: Average of the "First Friday of each of the previous 3 years"
3. January 8, 2016 was a Friday (the second Friday of 2016) and is in cell A1104
4. In cell B1104, the average should be computed as: Average of the "Second Friday of each of the previous 3 years"

I have solved this problem with the help of the PowerPivot. You may refer to my solution in this workbook.

Show Slicer selection on a Graph

{6 Comments}

Assume a simple Sales dataset from which a Pivot Table has been created.  The Pivot Table has been sliced by two columns of the dataset.  To represent data pictorially, a Pivot Chart has been created from this Pivot Table and the chart is placed on a separate worksheet (of the same workbook).  Now let's say, a user makes a few slicer selections on the Pivot Table worksheet.  When one now clicks on the Pivot Chart worksheet, one does not see what selections were made in the slicers (which are placed on the Pivot Table worksheet).  So one has to go back and forth between the two worksheets to keep track of the slicer selections made.  One may want to view the slicer selections made on the Pivot Chart as well.  Changes made in the slicer selections should automatically reflect on the Pivot Chart worksheet.

This can be accomplished by using the PowerPivot tool and CUBE functions (available in Excel 2007 + versions).  You may download the solution workbook from here.

Compute “running total in” across years in a Pivot Table

{2 Comments}

Assume quantity sold date by date and City in a three column database.  The objective is to determine year wise, month wise and City wise running total of quantity sold in a Pivot Table.

The issue which will arise with generating this result in a Pivot Table will be that the Show Values As > Running Total in, resets the quantity sold to 0 when the year changes.

This issue can be overcome by writing DAX formulas in a Power Pivot.  You may refer to my solution in this workbook.
