I'm trying to build a pivot table where one column shows the rolling average of the last 6 cells in another column but I can't get it to work.
Any hints where to start?
Like #pnuts said, don't do it inside a pivot table. In a pivot table, you should not think in terms of rows and columns, but in terms of dimensions and measures. Depending on the current arrangement of dimensions of measures, as well as the filters on the dimensions (visible or invisible), the moving average could show very wrong results.
Instead, construct your moving average as a column associated with the pivot source range.
If you must do it from inside a pivot table, you can try using the GETPIVOTDATA() function, but I predict the exact expression could get very convoluted.

SECOND IMAGE CLICK NUMBER 1 I Want To Transpose Row Value Range A2:A50 To Column CZ2 To BC2. Formula Should Be Given IN CZ2. AND VALUE SHOULD GET IN REVERSE OR LEFT COLUMNS.[First IMAGE Click Number 2] 2. If I Give Transpose (AO2:AO50) In CZ2 it Will go range from CZ2 To EW2. I Want Transpose in Reverse Columns. If I Increase Row Value AO2:AO60 It Should Flow Towards Left From CZ2 To AS2. I Mean Transpose Should work towards Left Side Columns. Its Ok with any other formula If Not Transpose. Hope My Question is Understandable. Someone Help Me Out. Thank You In Advance.
It's not clear why you would want to do this. However, the end goal can be achieved by placing the following formula in cell B2 (not CZ2):
=ArrayFormula(IFERROR(VLOOKUP(COLUMNS(B1:1)-COLUMN(B1:1)+ROW(A2)+1,{ROW(A2:A),A2:A},2,FALSE)))
Try it and you'll see what I mean.
The formula is written to be flexible. So if you add or subtract data from A2:A, the value in A2 will always be in Row 2 of the last column to the right in the sheet; and all other values will work backward from there.
If you always want to start to backward progression in Column CZ and Column CZ is not (or may not always be) your rightmost column, you can use this version:
=ArrayFormula(IFERROR(VLOOKUP(COLUMN(CZ1)-COLUMN(B1:CZ1)+ROW(A2)+1,{ROW(A2:A),A2:A},2,FALSE)))
Just understand that, if you don't have columns at least through Column CZ, this formula will fail to work as expected.
I recommend using the first formula I supplied above, since it will always work, no matter how many columns there are, filling backward as far as to the formula column (B2) as needed.
Understand also that if you have more than 103 rows of data in A2:A, that would be more than could fit between B2 and CZ2; so only the first 103 would be displayed.
ADDENDUM (after reading first two comments below):
The principle is the same if you want to run results from "CZ to BC"; only in this case, you want to limit the results to no more than 50.
Place the following formula in BC2:
=ArrayFormula(IFERROR(VLOOKUP(SEQUENCE(1,50,ROW(A2)+50-1,-1),{ROW(A2:A),A2:A},2,FALSE)))
To reiterate, you cannot run formulas that will fill or columns backward. (Even if the sheet is set to right-to-left font with Column A appearing at the far right, the formula is still filling A-Z according to that setup.) However, if you know that you want a 50-column range reserved and you want the answers to go backward, this can still be achieved by placing the formula in the first of the 50 columns rather than the last, as I have proposed above.
I am trying to replicate the plot below (done with ggplot in R) using Tableau:
However, I can't see how I can subset the plot so it fits the screen using Tableau. Using Tableau, this is what I get:
I've attempted adding the following but it stops plotting the histograms and ends up messier:
Row Divider (Discrete):
INT((INDEX()-1)/(ROUND(SQRT(SIZE()))))
Columns Divider (Discrete):
(INDEX()-1)%(ROUND(SQRT(SIZE())))
How can I achieve the plot in R using Tableau?
P.S.: The datasets are different in case you were wondering why Monday doesn't look the same.
You're on the right path using Row-Column divider, but you need to go some step further using the small multiple technique.
For instance, you need to move WEEKDAY in the detail mark and then, use column and row divider in column and row shelf.
Doing so, you'll also need to right-click on CNT/Ride Id Hash) and compute it with WEEKDAY.
Here's a cool guide by a Tableau Zen master showing how to work with this tecnique: https://www.vizwiz.com/2016/03/tableau-tip-tuesday-how-to-create-small.html
I'm trying to count the number of empty cells that exist in a column between each non-empty cell but haven't been able to work out how.
Using this, I'm also trying to find the largest "empty distances" and locate the cell in the center of these distances.
The sheet I'm working with lists a set of marker colors and denotes the ones that are owned out of the full set of colors. I'm trying to find the largest ranges of missing colors and then find the colors in the middle of those ranges in order to find a handful of markers that would best help to fill out the spectrum.
Columns 1-6 are information- Column 7 marks whether the color is owned:
I may have an answer that helps you.
I could only get it to work using a helper column, but someone may know how to eliminate that requirement.
The helper column creates an array, basically listing the row numbers of the rows that have an "x" in your column B.
The main formula then measures the gap between each of these listed row numbers. It also checks the gap before the first "x", and after the last "x". Note that I have the data starting on row 2, which complicates the formula, but makes the sample sheet clearer - this can easily be changed to row 1 if you prefer.
={F2-1;
query(ArrayFormula(if(isnumber(F3:F),F3:F-F2:F-1,"")),
"select Col1 where Col1 > 0",0);
counta(A2:A)-indirect("F"&COUNTA(F$2:F))}
See a sample sheet here:
https://docs.google.com/spreadsheets/d/19QUFGRqTT6BqOsBrEBpTIxQCeNdRa5mzXhxQpCZ8sV4/edit?usp=sharing
Then I used a second formula to calculate the max gap between "x"s, (or before the first or after the last x).
Note that calculating the midpoint of the gaps, and doing a lookup of the corresponding mid-point colour, is something that can be added to this answer, if you share a sample copy of your sheet and share it for editing.
Let me know if this helps. I'll add more explanation to describe what the formula is doing tomorrow.
And I'll provide a second tab with the formulas adjusted to work with data beginning on row 1.
You can also get the lengths of the gaps using Frequency:
=ArrayFormula(frequency(if((B1:B20<>"X")*(A1:A20<>""),row(B1:B20)),if((B1:B20="X")*(A1:A20<>""),row(B1:B20))))
but finding the centres of the gaps and allowing for equal-sized gaps is more difficult.
This should find the position of the "X" at the end of the longest gap:
=ArrayFormula(
sum(frequency(if((B1:B20<>"X")*(A1:A20<>""),row(B1:B20)),
if((B1:B20="X")*(A1:A20<>""),row(B1:B20)))*(sequence(countif(B1:B20,"X")+1,1)<=
match(max(frequency(if((B1:B20<>"X")*(A1:A20<>""),row(B1:B20)),
if((B1:B20="X")*(A1:A20<>""),row(B1:B20)))),frequency(if((B1:B20<>"X")*(A1:A20<>""),row(B1:B20)),
if((B1:B20="X")*(A1:A20<>""),row(B1:B20))),0)))+
countif(sequence(countif(B1:B20,"X")+1,1),"<="&
match(max(frequency(if((B1:B20<>"X")*(A1:A20<>""),row(B1:B20)),
if((B1:B20="X")*(A1:A20<>""),row(B1:B20)))),frequency(if((B1:B20<>"X")*(A1:A20<>""),row(B1:B20)),
if((B1:B20="X")*(A1:A20<>""),row(B1:B20))),0))
)
and then it should just be a case of working backwards from there to the centre of the longest gap. However the formula needs further refinement to deal with the cases
(1) Where the longest gap is after the last "X"
(2) Where there is a tie for the longest gap
(3) Where there is a need to list the longest, second longest, third longest gap etc.
In Google Sheets I want to get the sum of the first 2 columns and display that result in the 3rd column all the way down. Like this:
I'm hoping for a solution that does this in one step. As I have many rows.
Edit: I am aware of this question: Apply formula to the entire column and it appears to only cover part of what I am asking.
Try:
=arrayformula(if(A2:A<>"",ADD(A2:A,B2:B),""))
I have a pivot table with a couple slicers applied to it. The issue I'm having is when I double click a value in the pivot table, the sheet that's created has the appropriate pivot table filters applied, but not the slicer filters. Is there a way to do this without a macro?
Thanks!
Did some more googling and found a way to pose the question that got me an answer. Here's the relevant site http://blog.contextures.com/archives/2012/03/22/drill-to-detail-with-excel-slicer-filters/
In short, you have to use a macro to apply slicer filters to the drill down.
