I'm trying to rank some data in spotfire, and I'm having a bit of trouble writing a formula to calculate it. Here's a breakdown of what I am working with.
Group: the test group
SNP: what SNP I am looking at
Count: how many counts I get for the specific SNP
What I'd like to do is rank the average # of counts that are present for each SNP, within the group. Thus, I could then see, within a group, which SNP ranks #1, #2, etc.
Thanks!
TL;DR Disclaimer: You can do this, though if you are changing your cross table frequently, it may become a giant hassle. Make sure to double-check that logic is what you'd expect after any modification. Proceed with caution.
The basis of the Custom Expression you seem to be looking for is as follows:
Max(DenseRank(Count() OVER (Intersect([Group],[SNP])),"desc",[Group]))
This gives the total count of rows instead of the average; I was uncertain if "Count" was supposed to be a column or not. If you really do want to turn it into an average, make sure to adjust accordingly.
If all you have is the Group and the SNP nested on the left, you're done and good to go.
First issue, when you want to filter it down, it gives you the dense rank of only those in the filtered set. In some cases this is good, and what you're looking for; in others, it isn't. If you want it to hold fast to its value, regardless of filtering, you can use the same logic, but throw it in a Calculated column, instead of in the custom expression. Then, in your CrossTable Aggregation, get the max of the Calculated Column value.
Calculated Column:
DenseRank(Count() OVER (Intersect([Group],[SNP])),"desc",[Group])
Second Issue: You want to pivot by something other than Group and SNP. Perhaps, for example, by date? If you throw the Date across the top, it's going to show the same numbers for every month -- the overall numbers. This is not particularly helpful.
To a certain extent, Spotfire's Custom Expressions can handle this modification. If you switch between using a single column, you could use the following:
Max(DenseRank(Count() OVER (Intersect([${Axis.Columns.ShortDisplayName}],[Group],[SNP])),"desc",[Group],[${Axis.Columns.ShortDisplayName}]))
That would automatically pull in the column from the top, and show you the ranking for each individual process date.
However, if you start nesting, using hierarchies, renaming your columns, or having multiple aggregations and throwing (Column Names) across the top, you're going to start having to pay a great deal to your custom expression. You'll need to do some form of string replacement around the Axis.Column, or use expression instead of Short Names, and get rid of Nests, etc.
Any layer of complexity will require this sort of analysis, so if your end-users have access to modify the pivot table... honestly, I probably wouldn't give them this column.
Third Issue: I don't know if this is an issue, exactly, but you said "Average Counts" -- Average per day? Per Month? When averaging, you will need to decide if, for example, a month is the total number of days in month or the number of days that particular payor had data. However you decide to aggregate it, make sure you're doing it on the right level.
For the record, I liked the premise of this question; it's something I'd thought would be useful before, but never took the time to try to implement, since sorting a column or limiting a table to only show the top 10 values is much simpler

I know drawdown isn't the correct word, but I also don't know the correct word to use so if you know it tell me as well please.
What I'm trying to do is for a list of open work orders, apply an incoming PO to fill that work order, and then when the quantity in that first PO is exhausted roll to the next PO. I have tables that look similar to these, although the order of the columns can change if need be. Typically the order of the work orders are sorted in date order, as well as PO. Double points if this can be achieved without using VBA, and could just be a formula. Helper columns and tables are also fine. thanks!
then my PO's are something like this
and I would like the result to look something like this (although the remaining column isn't necessary, it would be helpful)
Problem is straightforward, but solution is escaping. Hopefully some master here can provide insight.
I have a big data grid with prices. Those prices are ordered by location (rows) and business name (cols). I need to match the location/row by looking at two criteria (location name and a second column). Once the matching row is found (there will always be a match), I need to get the minimum/lowest price from two ranges within the grid.
The last point is the real challenge. Unlike a normal INDEX or MINIFS scenario, the columns I need to MIN aren't contiguous... for example, I need to know what the MIN value is between I4:J1331 and Q4:U1331. It's not an intersection, it's a contiguous set of values across two different arrays.
You're probably saying "hey, why don't you just reorder your table to make them contiguous"... not an option. I have a lot of data, and this spreadsheet is used for a bunch of other stuff. So, I have to work with the format I have, and that means figuring out how to do a lookup/min across multiple non-contiguous ranges. My latest attempt:
=MINIFS(AND($I$4:$J$1331,$K$4:$P$1331),$B$4:$B$1331,$A2,$E$4:$E$1331,$B2)
Didn't work, but it should make it more clear what I'm trying to do. There has GOT to be an easy way to just tell excel "use these two ranges instead of one".
Thanks,
Rick
Figured it out. For anyone else who's interested, there doesn't seem to be any easy way to just "AND" arrays together for a search (Hello MS, backlog please). So, what I did instead was to just create multiple INDEX/MATCH arrays inside of a MIN function and take the result. Like this:
MIN((INDEX/MATCH ARRAY 1),(INDEX/MATCH ARRAY 2))
They both have identical criteria, the only difference is the set of arrays being indexed in each function. That basically gives me this:
MIN((match array),(match array))
And Min can then pull the lowest value from either.
Not as elegant as I'd like... lots of redundant code, but at least it works.

I'm not able to take the means for a large dataset given that the amount of attributes is irregular.
I have posted a simplified case for the problem. It explains the problem very well.
An idea that I came up with: Make a filter to condition on a single attribute. However, still, I don't see a way to do this in an efficient way (other then doing it all by hand).
see excel file:
All help is much appreciated.
I'm basically looking for a function/method to achieve taking means of all different attributes conditioned on each person for a large dataset without doing it by hand.
You can use AVERAGEIFS() inside an IF:
=IF(OR(A2<>A1,B2<>B1),AVERAGEIFS(C:C,A:A,A2,B:B,B2),"")
the ifrst part of the if tests whether the row starts a new group either by the person or the attribute changing. Then it uses AVERAGEIFS() to return the correct average of that group. otherwise it returns a blank
What you want to do can be accomplished very simply with a pivot table.
Simply select one of the cells inside the range of data you want to process(See the video for general use of a pivot table https://www.youtube.com/watch?v=iCiayB6GrpQ )
go the insert tab and insert pivot table.
Once you have it, simply check people, attribute, and values. Then drag people and attribute into rows, drag valut into the values window, select the drop down list and change it from sum of value to average and you should be done. https://i.stack.imgur.com/nYEzw.png
I have been working on a small project. I am trying to display all the results in the same row without NULL values. I've written a small expression to remove the Null values already "=IIF(IsNothing(Fields!RegisterNo.Value),True,False)". However, the rows seem to be moving one level down as it is displayed in the picture ResultMatrix1. I want the results to be on the same level. Can you please tell me if this is possible and how I can achieve it. Is it something to do with the groupings or something else?
Design Groupings
By default, when you create a table, there is a Row Group called "Details" that is not actually grouped by anything. This causes it to produce one row for each row from the dataset. Since you are trying to group these, you need to make sure that innermost group is grouped by your Staff Ref No.
In the lower-right cell, you may need to change the expression to use a Max function. This will simply avoid arbitrarily showing blanks when they happen to be sorted before a real value within that group.
Hello i'm having problems with getting this to work. What i'm trying to do is when you insert a set of measurements i want excel to show the ( In this case products) which are closest to those measurements.
here is a picture:
The result i'm trying to reach is when you type in the measurements you get product(s) and the manufacturer which are closest to those measurements.
Any help is greatly appreciated.
In essence, what you are after is an index+match function. It will allow you to find a value in one list, given a corresponding variable. In this case, given a measurement, it will find a manufacturer and product combo in your list.
Your problem is that you will need to adapt your data to allow for this. For example, you need to decide whether you only want the closest match for measurements or if you need the closest match that is greater than the measurement you provide.
It is also possible that you'll need to split your measurement column into two different columns (unless all you need is the total area irrespective of individual lengths).
You could potentially avoid the index+match by using conditional formatting, but that would still require the data manipulation.
Given the information you provided, the answer will never be much more informative than this. But this should get you started and the following steps can be made easier with help from google.
