The blog posting 'The Power Of Yellow' describes how Show Alternatives can be used to highlight data excluded by a selection on a field that would otherwise be included.  This QlikView application illustrates this functionality.

This tequnique can be useful in making immediately apparent something that would otherwise be hard to spot, or require extra clicks to remove selections.

For a full description of how and why the feature can be used please see the original blog post at: http://www.quickintelligence.co.uk/the-power-of-yellow/

What it is used for?

The Qualify statement is used for switching on the qualification of field names, i.e. field names will get the table name as a prefix.’

In situation where we have two (or more) Tables with the same field names:

Product	Payment

The Qualify statement will assign name of the Table to fields:

Remember

• To use the script below the Excel file must be saved in the same folder that your qvd file

        Otherwise you will need to make changes the this path - [Qualify.xlsx]

QUALIFY *;
Product:
LOAD [Serial No],
Category,
Value
FROM
Qualify.xlsx
(ooxml, embedded labels, table is Product);

QUALIFY *;
Payment:
LOAD [Serial No],
Category,
Value
FROM
Qualify.xlsx
(ooxml, embedded labels, table is Payment);

The Outcome:

Table Viewer:

Read only if you need to know more....

If we have not used ‘QUALIFY’ statement in situation as above Qlikview would map both of the Tables with outcome like below:

The end result  -merge of those two Tables is correct only for the “Serial No” fields

The “Value” and “Category” fields although merged is none of use to us.

To fix this we can only Qualify fields that we do not want to associated:

QUALIFY Category,
Value;
Product:
LOAD [Serial No],
Category,
Value
FROM
Qualify.xlsx
(ooxml, embedded labels, table is Product);

QUALIFY Category,
Value;
Payment:
LOAD [Serial No],
Category,
Value
FROM
Qualify.xlsx
(ooxml, embedded labels, table is Payment);

or by using UNQUALIFY statement:

(which works as opposite to QUALIFY)

QUALIFY *;
UNQUALIFY [Serial No];
Product:
LOAD [Serial No],
Category,
Value
FROM
Qualify.xlsx
(ooxml, embedded labels, table is Product);

QUALIFY *;
UNQUALIFY [Serial No];

Payment:
LOAD [Serial No],
Category,
Value
FROM
Qualify.xlsx
(ooxml, embedded labels, table is Payment);

In second example the ‘QUALIFY *’ part will add Table name to all fields and the UNQUALIFY statement will remove those names only from specified fields(this method is very useful if we got large numbers of fields)

Outcome is as below:

How To /Missing Manual(18 articles)

When showing data in a month on month style the current month can often have a large drop off.  This can be prevented by providing a run rate for the current month.  This is where the known values for the current period are extrapolated forward for the rest of the period, providing an estimate of where the period will end.  For example, if you have a value of 1000 on day 10 of a 30 day month, you could calculate a run rate of 3000 for the month.

This solution was created in response to a question on Qlik Community, which you can find here:

Definition:

Returns the number of dimension columns that have non-aggregation content. i.e. do not contain partial sums or collapsed aggregates.

A typical use is in attribute expressions, when you want to apply different cell formatting depending on aggregation level of data.

This function is only available in charts. For all chart types except pivot table it will return the number of dimensions in all rows except the total, which will be 0.

What does it mean?

We have Table with 4 dimensions(columns): Product,Category,Type,Sales

Now we want to create Pivot Table by using those Dimensions.

We are going to use only 3 of them(Product,Category,Type) and use 4th(Sales) in our expression.

The result is shown below:

This Pivot Table  has 3 dimensions so its maximum dimensionality is 3.

For better understating please see  table below.

The function is used to show on which dimensionality level each of the Pivot Table row is:

'Sugar' has dimensionality of 1 which is Total for that 'Product'.

'Salt' has dimensionality of 2 which is Total for each 'Category' of that 'Product'.

'Oil' has dimensionality of 3 which is single value for each 'Type' of the 'Product's' 'Category'.

So then more Dimension we use the greater dimensionality of our Pivot Table is.

Practical use:

1) To show the level of dimensionality:

Expression:

if(Dimensionality()=1 ,RGB(151,255,255),if(Dimensionality()=2 ,RGB(0,238,0),if(Dimensionality()=3,RGB(255,130,171))))

2) Highlight background of rows which on each level  fall into certain condition:

Expression:

if(Dimensionality()=1 and sum(Sales)<150,RGB(151,255,255),if(Dimensionality()=2 and sum(Sales)<=20,RGB(0,238,0),if(Dimensionality()=3 and Sum(Sales)<=20,RGB(255,130,171))))

LEVEL1 --> Values <140	LEVEL 2 --> Values <=20	LEVEL 3 --> Values <=20

Remember

• To use the script below the Excel file must be saved in the same folder that your qvd file

        Otherwise you will need to make changes the this path - [Dimensionality.xlsx]

What it is used for?

To return values from another table field based on matching field value from current table.

Typically used when only one field records from another table are needed.

(You are dropping this (second) table later on.(see below) )

How does it look like?

How is it design?

• dual - this is not actual part of the function but  prefix used to indicate what kind of value this function returns –in this case it means that this function can return numbers and characters
• Lookup - function name

and four arguments:

• field_name – is the name of a field in the other table – in the table where we want the value to take from
• match_field_name- is the name of a field in the other table – this is the matching value to the next argument

                                                                        <---->

• match_field_value - is the name of field in the this table-matching with previous argument
• [, table_name] - This is name of the other table (this argument is optional if omitted current table is used)

Preparation:

We have got two tables in Excel file.

For convenience let’s call them ‘Table1’ and ‘Table2’:

Table1	Table2

Remember

• To use the script below the Excel file must be saved in the same folder that your qvd file

        Otherwise you will need to make changes the this path - [LookUp.xlsx]

Table2:
LOAD  Category,
Sales,
Country
FROM
[Lookup.xlsx]
(ooxml, embedded labels, table is Table2);

Table1:
LOAD Category,
Lookup('Country','Category',Category,'Table2') as Country

FROM
[Lookup.xlsx]
(ooxml, embedded labels, table is Table1);
drop table Table2;

Remember  to... Look Up!

(This is where the name of this function has another meaning)

Table 2 must be above Table1!

or after Reload you will get script error.

How does it work?

Formula:

Script:

Table2:
LOAD  Category,
Sales,
Country
FROM
[Lookup.xls]
(ooxml, embedded labels, table is Table2);

Table1:
LOAD Category,
Lookup('Country','Category',Category,'Table2') as Country

FROM
[Lookup.xlsx]
(ooxml, embedded labels, table is Table1);
drop table Table2;

Remember:

• First two arguments and the last one must be enclosed in apostrophes '' .
• You need to drop Table2 using: drop table statement or all fields from Table1 will be loaded, bringing unexpected results.

The final tables you should see are like this:

Pros:

• You can return any field from second table based on any matched field from first table -

You can look at first field in the table to return third one and to look at third field to return the first one.

Cons:

• Little bit confusing with the syntax
• Slower than Apply Map
• No ‘False’ return – If there is no match a Null is returned.

      To overcome this drawback we can wrap the formula in IF function:

    If(isnull(Lookup('Country','Category',Category,'Table2')),'No                      match',Lookup('Country','Category',Category,'Table2')) As Country

Exercise :

Return field ‘Sales’ from Table2 by using ‘Category’ field from Table1.

(Answer at the end of this article)

Appendix:

For many of you coming from Excel world and working with VLOOKUP this syntax is little difficult to understand at first.

Why we can not have:

Take value from this table go to the another table matched the field and return what we need?

So the syntax would have been:

Lookup(Category,Table2,Category,Country)

Would this not be simpler?

This is open question so please state your case....

Answer to Exercise:

Lookup('Sales','Category',Category,'Table2') as Sales

This article provides an overview of Benford's law.

For more information about Benford's Law, please visit the link below.

Benford's law - Wikipedia, the free encyclopedia

Benford’s Law can often serve as an indicator of fraudulent data and assist in auditing accounting records. It describes the distribution of the first digits in a dataset. For example, a sales figure of $11,292 would be represented by the digit 1.

In the chart above, we can see that the distribution of the digit 1 in the actual data is higher than the distribution predicted by Benford's Law for the digit 1. This indicates that we need to investigate the transactions of the sales figures that start with the digit 1.

Please refer to the attached application.

Additionally, please see:

Bollinger Bands

Control Chart

Bullet points:

• MaxString and MinString belongs to Qlikview String Aggregation function.
• They are equivalent to MAX and MIN for integers
• They return the highest and lowest string value

What actually a value of a string?

This is the value described by ANSI character standard where 0 ( NULL) is equal  to 0 and ÿ to 255.

(For full ANSI character set please attached dosument)

Taking only the standard English alphabet (A-z)  ‘A’ will be the MIN and ‘z’ will be the MAX.

Remember:

In ANSI standard A < a and Z < z

(A=65,Z=90,a=97,z=122)

Language specific characters will be not recognized in the place where they are in your alphabet but they will be 'pushed' to the end

(see ANSI table)

MinString and MaxString works on dimensions (columns) only so you cannot use is to evaluate single character or strings .

(MaxString(‘a’,’z’…) is not supported

Examples:

1)    MIN & MAX (textbox)

Data	Expression	Results
	MinString(Category) MaxString(Category)

2) MIN and MAX of String per group (Straight table)

Data	Expression	Result
	MinString(Category) MaxString(Category)

3) With condition:

Return Max and Min string based on another column

We are looking for MIN and MAX string value from column Category where Country='Poland'

Data	Expression	Solution	Result
	MinString( if(Country='Poland', Category, null()) ) MaxString( if(Country='Poland', Category, null()) )

4) With LEFT/RIGHT

When used with LEFT the result will be the same as without as the value will be still based on first characters.

Data	Expression	Solution	Result
	=MinString( Right(Country,1)) =MaxString( Right(Country,1))

5) With MID

6) With Substring

When our data are little scrambled -TextBetween will return string between '.' and end of the row.

Data	Expression	Result
	=MinString(TextBetween(Country,'.','',1)) =MaxString(TextBetween(Country,'.','',1))

7) In set analysis

When Criteria of Sales is 2 return Country with highest and lowest string Value

😎 With Aggr()

For each Country return lowest and highest Category string value.

If know about other ways of using these functions please let me know.

Have you ever wondered how the examples from the Qlikview help may look like?

Please see below and enjoy responsibly...

Before () and After()

Description

Returns the value of expression evaluated with a pivot table's dimension values as they appear in the column before the current column within a row segment in the pivot table. This function returns NULL in all chart types except pivot tables.

On the first column of a row segment a NULL value will be returned, as there is no column before this one.

If the table is one-dimensional or if the expression is preceded by the total qualifier, the current row segment is always equal to the entire row.

If the pivot table has multiple horizontal dimensions, the current row segment will include only columns with the same values as the current column in all dimension rows except for the row showing the last horizontal dimension of the inter field sort order. The inter field sort order for horizontal dimensions in pivot tables is defined simply by the order of the dimensions from top to bottom.

Specifying an offset greater than 1 lets you move the evaluation of expression to columns further to the left of the current column. A negative offset number will actually make the before function equivalent to a after function with the corresponding positive offset number. Specifying an offset of 0 will evaluate the expression on the current column. Recursive calls will return NULL.

By specifying a third parameter n greater than 1, the function will return not one but a range of n values, one for each of n table columns counting to the left from the original cell. In this form, the function can be used as an argument to any of the special Chart Range Functions.

• Returns value from preceding (Before)or following (After) column
• Returns values only in Pivot Table otherwise NULL.
• Works only with Horizontal dimension.
• Equivalent to below() and above() for vertical Pivot Table dimensions.

Data Model:

(Copy and Pasted below code into Edit Script window and reload)

LOAD * inline

[

Product ,Category ,Sales

Salt ,White, 30

Salt, Brown ,40

Salt ,Red ,30

Sugar ,White ,10

Sugar ,Brown ,20

Sugar ,Red ,20

Wine ,White ,40

Wine ,Brown ,30

Wine ,Red ,10

]

Example 1:

Let's build a Pivot Tables with Product as dimension and expressions as below:

The left hand side shows an ordinary use of Sales the right hand side result from our new expression.

                sum( Sales )    ----------->  before(sum( Sales ) )

Salt value has been assigned to Sugar,

Sugar to Wine,

Salt  is now NULL .(there is no column before this one)

                sum( Sales )    -----------> after(sum( Sales ) )

Here we see the opposite result:

Sugar value has been assigned to Salt,

Wine to Sugar

and Wine is  NULL (no column after this one)

Example 2

Specifying the second criteria as 2 we shifted all values by 2 columns right or left.

                                before( sum( Sales ), 2 )

                                after( sum( Sales ), 2 )

Example 3

before(total sum( Sales ) )

after(total sum( Sales ) )

When using with one dimension this expression returns values as if we have used ordinary  before/after (Sum(Sales))

For more than one dimension the return value will be based on last column of the first(top) dimension and then appropriate columns for the second dimension.

Salt and Sugar have been omitted leaving Wine as the last column

Example 4

rangesum (Before(sum(Sales),1,2))

RangeSum() takes 3 parameters

-expression ---> Before/After(sum(Sales),

-offset of columns--->1

-number of columns to sum--->2

                                                                  sum(Sales)                            rangesum (Before(sum(Sales),1,2))

In our example we are shifting our calculation one column to the right:

-Salt -  As there is no column before Salt this column has been ignored

-Sugar -we are shifting our calculation one column to the left (Salt)  and are summing previous two columns.

As there is no column before Salt the final result is value of Salt alone.

-Wine- by shifting calculations one column to the left(Sugar) and summing two previous columns we getting 100+50=150

                    sum(Sales)                            rangesum (after(sum(Sales),1,2)

In this example we are shifting our calculation one column to the right:

-Wine -  As there is no column after Salt this column has been ignored

-Sugar -we are shifting our calculation one column to the right(Wine) and aresumming previous two columns.

As there is no column after Wine the final result is value of Wine alone.

-Salt- by shifting calculations one column to the right(Sugar) and summing two previous columns we getting 50+80=130

This article provides an overview of Bollinger Bands.

Many traders use Bollinger Bands to determine overbought and oversold levels, selling when price touches the upper Bollinger Band and buying when it hits the lower Bollinger Band.

Components of Bollinger Bands

1) Avg Stock Price

    It's simple Avg of stock price.

2) Moving Avg of Stock Price

    It's Moving Avg of Stock price over last n Period

3) Upper Band

    Moving Avg of Stock Price + Std Deviation over last n Period * Std Deviation Multiplier

4) Lower Band

    Moving Avg of Stock Price - Std Deviation over last n Period * Std Deviation Multiplier

Note :

• Users can select their own moving period and standard deviation multiplier.

• When viewing the Bollinger Bands on a weekly basis, users can choose a moving period ranging from 1 to 50.

• When viewing the Bollinger Bands on a monthly basis, users can select a moving period ranging from 1 to 10.

• The standard deviation multiplier can be inputted from 0.01 to 4.

Please see below and enjoy responsibly...

Valueloop() & VaueList()

Both of those functions belong to Synthetic Dimension Functions.

Synthetic Dimension is a type of Calculated Dimension

- the difference between "standard" Calculated Dimension and Synthetic one is that

the standard dimensions are based on values from existing fields

whereas for Synthetic Dimensions those values are created "on the fly".

The drawback here is that you can not mix standard dimensions with synthetic in the way you would expect.

(please see "Practical use").

ValueLoop()

Used:

Back End -No

Front End - Yes

Description(Qlikview Help)

Returns a set of iterated values which, when used in a calculated dimension, will form a synthetic dimension.

The values generated will start with the from value and end with the to value including intermediate values in increments of step. In charts with a synthetic dimension created with the valueloop function it is possible to reference the dimension value corresponding to a specific expression cell by restating the valuloop function with the same parameters in the chart expression. The function may of course be used anywhere in the layout, but apart from when used for synthetic dimensions it will only be meaningful inside an aggregation function

Create series of numbers in a range given by criteria.

from - first value

to - last value

step - intermediate values criteria.

When step is missing 1 is assumed

Qlikview help examples are very straightforwards and easy to understand:

Example 1	Example 2	Example 3
valueloop ( 1, 3 ) From 1 to 3, (step is omitted so 1 is assumed):	valueloop ( 1, 5, 2 ) From 1 to 5, step 2: 1,1+2=3,3+2=5	valueloop ( 11 ) returns the value 11

Practical use

Example 1

If you need to provide calculations to check if the MOD of values from 0 to 100 with step 5 is divided by 10 without remainder

Create Dimension: ValueLoop(0,100,5)

and Expression: if(mod(ValueLoop(0,100,5),10)=0,'OK', 'No OK')

qlikfreak.wordpress.com/2014/06/17/infographics-in-qlikview-vol-2/

ValueList()

Used:

Back End -No

Front End - Yes

Description(Qlikview Help)

Returns a set of listed values which, when used in a calculated dimension,

will form a synthetic dimension. In charts with a synthetic dimension created with the valuelist function it is possible to reference the dimension value corresponding to a specific expression cell by restating the valuelist function with the same parameters in the chart expression. The function may of course be used anywhere in the layout, but apart from when used for synthetic dimensions it will only be meaningful inside an aggregation function

Create series of values from given list

v1 - list of values

Again, both of those examples are very easy to understand:

Header 1	Header 2
valuelist ( 1, 10, 100 )

Header 1	Header 2
valuelist ( 'a', 'xyz', 55 )

Practical use

Data Model

LOAD Date,

Year(Date) as Year,

Values

inline [

Date, Values

01/01/2009, 1

11/04/2009, 2

20/07/2009, 2

16/05/2010, 2

24/08/2010, 1

02/12/2010, 1

]

The usual way of creating straight table is be to add Year as Dimension and sum(Values) as expression.

This will return value for each Year.

But if we want o use Synthetic Dimension in the same way this will return only one Total value for both years.

One of the way to use this function is to create list (similar to Statistics Box) with your own KPI's:

and then use nested IF statement to create your Metrics

=if(ValueList('Sum','Count','Average')='Sum',Sum(Values),

if(ValueList('Sum','Count','Average')='Count',Count(Values),Avg(Values)))

to get below result:

As nesting IF's can be tricky and cumbersome beyond 2 or 3 criteria we can use Pick/Match functions to improve our calculations:

=pick(match(ValueList('Sum','Count','Average'),'Sum','Count','Average')

,Sum(Values),Count(Values),Avg(Values))

Conclusion:

Although both of those function are not very often used

(they did not make to final 30 of  rwunderlich survey

Help with QV Function Survey‌   

you can find a practical way of using them.

How To /Missing Manual(19 articles)

Hi,

The Following blog was inspired by a recent post that allowed me to exercise my brain into trying something new

(link to thread: Qlikview Chart)

Below is one of the two charts to be achieved in Qlikview. This led / music equalizer style looked pretty cool so I had to try

I finished with a chart like this. Close enough I'd say.

You can also adjust the number of bands you wish to see on the chart, but make sure you adjust the percentage scales for background colors

How did we achieve this chart?

The Idea is to break each value into multiple segments and then use background expression to make only alternate segments visible.

Simple isn't it.

So we've basically turned a simple single dimension one expression chart into a Stacked Chart with two Dimensions and one Expression.

Apply the same approach with Grid Charts which allow other visualization possibilities.

These are just for your viewing pleasure, hope you enjoy playing with them as much as I did.

Happy Qlik'in

Cheers

This example shows an alternative way of showing current selections in your applications.

It is useful to see a complete list of all selections on every screen, but this can take a lot of space - leaving less room for analysis.

This shared QlikView uses a text box that sits neatly at the top of the page and shows what selections are currently in play.  A large current selections box can then be shown or hidden dynamically by clicking the text box.  This allows selections to be modified and removed in the standard way.

Using text boxes in itself can be a good way of conveying a lot of information in a small space.  Attaching actions to items other than Buttons is a good way to a cleaner 'flat' UI.  Combining the two things can work really well - as I hope this example shows.

Prologue...

Firstly I would like to say that probably it would be easier to call this function Horizontal Dimensionality (or HDim or even SecDim)

This could clear some clouds - when you first see this function you may feel that this another level for dimensionality function.

(for those who wants to know more about the dimensionality function please see this document

How to use - Dimensionality()

What it is used for?

Returns the number of dimension pivot table rows that have non-aggregation content. i.e. do not contain partial sums or collapsed aggregates. This function is the equivalent of the dimensionality function for horizontal pivot table dimensions.

The secondarydimensionality() function always returns 0 when used outside of pivot tables.

What does it mean?

Where dimensionality shows number of vertical dimensions, secondarydimensionality shows  number of horizontal dimensions.

Lets take our sample data.

We have four dimensions(columns):

Product,Category,Type and Sales.

Each Product have 2 Categories

Each Category can have up to 3 Types

Let's create Pivot Table using 3 of those Dimension Product,Category and Type and use  Sales as our Expression.

This Pivot Table  has 3 dimensions so its maximum dimensionality is 3.

'Sugar' has dimensionality of 1 which is Total for that 'Product'.

'Salt' has dimensionality of 2 which is Total for each 'Category' of that 'Product'.

'Oil' has dimensionality of 3 which is single value for each 'Type' of the 'Product's' 'Category'

So in few words : secondarydimensionality (and dimensionality) is the number of dimensions used in a Table

For better understating please see  table below:

The function is used to show on which dimensionality level each of the Pivot Table row is:

Practical use:

1) To show the level of dimensionality:

Expression:

if(secondaryDimensionality()=1,RGB(151,255,255),if(secondaryDimensionality()=2,RGB(0,238,0),

if(secondaryDimensionality()=3,RGB(255,130,171))))
