Loop for Field name

Hi there,

I am looking to create a dynamic label based on a field from one of my tables in the script. I have this field [AccountFriendlyName] that is potentially very lengthy. My goal is to create a new field that I can use that is formatted nicer than the original field. I think I am close with my loop but I seem to have an issue with defining a variable to a field name outside of a load.

Here is my code.

Let vNumOfSpaces = SubStringCount(AccountFriendlyName,' ');

Set vLabelAccountName = '';

Set i = 0;

Set vLastPosition = 0;

Do While i < $(vNumOfSpaces)

  Let vIndex = Index(AccountFriendlyName,' ',$(i)) - $(vLastPosition);

  If $(vIndex) < 12 then

  Trace $(vIndex);

  Next i;

  ELSEIF $(vIndex) > 12 then

  Let vLabel_AccountName =  $(vLabel_AccountName) & Mid(AccountFriendlyName,$(vLastPosition),$(vIndex)) & Chr(13);

  Set vLastPosition = $(vIndex);

  TRACE $(vIndex) & '_' & $(vLastPosition);

  Next i;

  ENDIF

Loop;

I found the solution I needed here: Displaying long labels on chart X-axis‌.

I edited Rob's code to better fit my needs since my field "AccountFriendlyName" isnt unique to the dataset.

Thank you to everyone who took the time to work on this problem!

See if this helps you. One of my colleague created this and I thought it was pretty impressive. See if this helps you.

Best,

Sunny

Hi Sunny,

Thanks for the quick reply. I can see where you colleague was going with this but I am looking for something a little more dynamic. They hard-coded each substringcount command up until 7. In my case I know I have some fields that go up to 12 but I really want to explore this using variables and a loop.

I think this method could work, but it is not ideal for my situation.

If you can provide a sample of data, we can play around with it to make it work.

Unfortunately I cant share the data I am using for AccountFriendlyName. But you can create your own sample data for this one field pretty easily.

I know I have some fields that have no spaces and others that have any number of spaces.

I listed my loop code so that should get you started.

thanks again.

I might create dummy data which won't work for you, if you can provide dummy data which is close to your data we won't have to go through the pain of re-doing this multiple times

Here is a file you can use. Again the words dont matter (these arent even english) but you get the idea.

(Not sure why I couldnt attach this, but consider each row 1 record).

I did not understand the if statement, but check

Table:

LOAD AccountFriendlyName

FROM

[https://community.qlik.com/thread/236104]

(html, codepage is 1252, embedded labels, table is @1);

FOR i = 1 to FieldValueCount('AccountFriendlyName')

  LET vNumOfSpaces = SubStringCount(FieldValue('AccountFriendlyName', $(i)), ' ');

  SET vLabelAccountName = '';

  SET j = 0;

  SET vLastPosition = 1;

  vLabel_AccountName$(i) = Null();

  FOR j = 1 to $(vNumOfSpaces)+1

  LET vIndex = Index(FieldValue('AccountFriendlyName', $(i)),' ',$(j));

  LET vLen = Len(FieldValue('AccountFriendlyName', $(i)))+1;

  LET vLabel_AccountName$(i) =  '$(vLabel_AccountName$(i))' & Trim(Mid(FieldValue('AccountFriendlyName', $(i)),$(vLastPosition),If($(vIndex) = 0, $(vLen), $(vIndex)) -$(vLastPosition))) & Chr(13);

  SET vLastPosition = $(vIndex);

  NEXT j;

NEXT i;

Thank you for taking the time to work on this.

I think we are getting closer but still not exactly what I need.

The If statement was to determine if the length of the word was longer than 12 characters. I dont always want to break the sentence at each space. I want to ensure I can fit as much of the sentence on each line as possible before adding the line break. So if a sentence was "I can climb to the top of the hill", I want it to be stored as

"I can climb

to the top

of the hill"

The reason for the breaks where they are is because I am using "12" as my character limit per row. If that falls in the middle of a word then the line break should occur at the previous space.

*I also noticed that you have these being stored as variables for each value. Ideally, I would like this to just be a field within the same table that AccountFriendlyName comes from just with a different name.

I could imagine that a different approach to split your records and put them together again (with a certain logic) could be easier. Take a look on the following:

//RawData:

//LOAD AccountFriendlyName

//FROM [https://community.qlik.com/thread/236104] (html, codepage is 1252, embedded labels, table is @1);

//store RawData into RawData.qvd (qvd);

RawData:

Load

    trim(AccountFriendlyName) as AccountFriendlyName, SubStringCount(trim(AccountFriendlyName), ' ') as NumberOfSpaces,

    Len(trim(AccountFriendlyName)) as RecordLength, recno() as RecNo

From RawData.qvd (qvd);

let vNumberOfChars = 12;

SplitRecords:

Load

    *, ceil(WordLengthWithSpaceCum / $(vNumberOfChars)) as WordCluster,

    RecNo & '|' & ceil(WordLengthWithSpaceCum / $(vNumberOfChars)) as WordKey;

Load

    *, len(SingleWord) as WordLength, if(RecNo <> peek('RecNo'), len(SingleWord), len(SingleWord) + peek('WordLengthCum')) as WordLengthCum,

    if(RecNo <> peek('RecNo'), len(SingleWord), len(SingleWord) + peek('WordLengthCum') + IterNo - 1) as WordLengthWithSpaceCum;

Load

    RecNo, iterno() as IterNo, subfield(AccountFriendlyName, ' ', iterno()) as SingleWord

Resident RawData while iterno() <= NumberOfSpaces + 1;

ConcatWords:

load

    rowno() as RowNo, WordKey, concat(SingleWord, ' ') as ConcatWords

resident SplitRecords group by WordKey;
