I have a data set which contains missing values as shown in the image. I would like to fill in the minimum value of the column in place of missing values. Which methods in Mathematica can be used to solve this issue and how can it be done?
Without seeing your code, it's hard to say anything specific, but in general you just need to put your column into a list l and take Min[l], then just fill in the missing values manually.

I need to display first and last selected value in list. I have listbox and when I pick date I got this result in list
I want to get in one box min value selected but when I use minString(Data) I got 22/2022 instead 303/202. And for max I need to get 306/2022.
Can anyone help please?
To get the Qlik engine to ignore the selected values you need to set analysis.
Firstly, you should be using a max() not a maxstring(). Max() will evaluate the maximum numerical value. Maxstring() will evaluate the maximum ascii values of the string (I think, anyone can correct me).
Secondly, the value 306/2022 in that list is grey which means it is no longer included in the dataset used for the visualisations being displayed. The white values are the values that are included, this is why min(Date) is returing 22/2022. 22/2022 is the minimum available (white) value in that list. 303/2022 is the minimum value of the excluded values in grey.
If you want to be able to reference the values even when the selections have caused it to be excluded (turned them grey) you need to modify your max() to max({1}).
{1} means look at all the data not just the selected data.
max({1} Date)
will return 306/2022 no matter what the selections are.
If you want to return 303/2022. The minimum of the excluded values and have that change dynamically when making other selections let me know and I can show you but I will require you to explain why you would want to that before I try figure it out :)
You can try using the OnOpen document trigger.

I'm trying to clear the entire cell if it doesn't contain a given keyword.
I've managed to do this for one column:
Table.ReplaceValue(#"PrevStep",each [#"My Column"], each if Text.PositionOf([#"My Column"],"keyword")>-1 then [#"My Column"] else null,Replacer.ReplaceValue,{"My Column"})
The problem is I need to iterate/repeat that step for a number of columns... the number of columns may vary and column names also may be different every time. I can have all those column names put into a list but I'm not able to use it.
The solution I'm looking for may look like this
for each ColNam in MyColumnsList
Table.ReplaceValue(#"PrevStep",each [#"ColNam"], each if Text.PositionOf([#"ColNam"],"keyword")>-1 then [#"ColNam"] else null,Replacer.ReplaceValue,MyColumnsList)
next
but this is not the VBA code but Power Query M - and of course the problem is with #PrevStep as I would see it like a recursions... again... do not know how to process.
Is the path I follow correct or should it be done some other way
Thanks

Unpivot your columns to turn all the columns into two columns. Apply your replacement to the single value column then pivot it back into the original format
I have the tbl format dataset for my project and I have one column where I have mixed values (although I can differentiate which are which) and I want to change the selected values of that column by dividing them by certain number, what is my best approach for this?
I have thought of writing mutate and somehow applying if statements inside but I couldn't figure out how to do it.
By leveraging the dplyr package, you can do
mutate_if(condition_to_check, funs(. / number_to_divide_by))
I'd like to use ArrayFormula to populate a column in spreadsheet, but when I Sort A->Z in a filter view, the ArrayFormula column vanishes. In some cases, the column includes a #REF! error about the range, and in some cases the column is just blank after the Sort. The following is a simplified version of what I'm trying to do (in my actual application, I'm doing a Vlookup to another sheet):
https://docs.google.com/spreadsheets/d/1XbqqedOjuSKuE-ZLIHNw59-r01EsNMpx7YVqOoxSOR4/edit?usp=sharing
The column 3 header uses an ArrayFormula to copy from column 1. If you go to the Filter 1 filter view, you'll note that column 3 is blank except for an error. This happens after I try to Sort Z->A on column 2. In my more complicated use-case, involving a Vlookup, after a Sort the column disappears entirely (leaving no #REF! error). Before sorting in both cases, everything is fine.
How do I make ArrayFormula values persist in filter views after sorting?
Thanks for your help!
I'm guessing that, because your references are normal (relative, not anchored/absolute), the range A2:A10 after sorting down turns into something absurd, like A7:A4, depending on actual sorted values.
Also, if you hover with your mouse on the #REF error, what does it tell you?
Anyway, try using absolute references in your formula:
=arrayformula({"Column 3"; A$2:A$10})
Edit
Fascinating. It's the first time I see this type of error. Taking it at face value, it seems that it's a limitation of Google Spreadsheets - you cannot use ARRAYFORMULAS spanning multiple rows inside sorted filter views, because, like I sort of guessed, it messes up the ARRAYFORMULA's range (as indicated by the fact that the formula is now in C4 instead of C1).
But that gives you also the solution: do not include the cell with the arrayformula in the filter view. Instead of making your filter view's target range A1:C20, make it A1:B20. Then the arrayformula in C1 will be untouched by the filter and will indeed continue to work.
I have found a solution for my usecase, in your case, it could be:
=arrayformula(if(row(C:C)=1;"Column 3";A:A))
But you'll need to consider the whole columns in your formulas.
Example
Have you tried A2:A?
If you don't put an ending row, means the end of the column.
It worked for me.
Cheers
I am trying to find a way to get a distinct count on a field that is being filtered by a territory without using grouping because of the fact that I need to then pass this value over to another report. The easiest way would be something like this:
distinctcount({Comm_Link.CmLi_Comm_CompanyId}) if {Company.Comp_Territory}='Atlanta'
But for obvious reasons that won't work. Any thoughts?
what you have to do is a running total. Right click on {Comm_Link.CmLi_Comm_CompanyId} insert running total, type of summary will be distinct count and on evaluate where says Use a formula type your condition {Company.Comp_Territory}="Atlanta"
your formula and approach is wrong.. I doubt whether your formula compiled with out any errors...
first create the value and then find the distinct count
if {Company.Comp_Territory}='Atlanta'
Then {Comm_Link.CmLi_Comm_CompanyId}
Now in footer write or you can get it by right click on the filed.
distinctcount({Comm_Link.CmLi_Comm_CompanyId})
