Last Friday we asked the following Qlik Data Architect certification practice question about aggregations in Qlik Sense with the Aggr function:. We have a straight table with an order overview, in which qlikview aggr can see the PartnerIDhow many orders they have placed, the lowest order value and the highest order value, qlikview aggr.

Aggr returns an array of values for the expression calculated over the stated dimension or dimensions. For example, the maximum value of sales, per customer, per region. The Aggr function is used for nested aggregations, in which its first parameter the inner aggregation is calculated once per dimensional value. The dimensions are specified in the second parameter and subsequent parameters. In addition, the Aggr function should be enclosed in an outer aggregation function, using the array of results from the Aggr function as input to the aggregation in which it is nested.

Aggr returns an array of values for the expression calculated over the stated dimension or dimensions. For example, the maximum value of sales, per customer, per region. The Aggr function is used for nested aggregations, in which its first parameter the inner aggregation is calculated once per dimensional value. The dimensions are specified in the second parameter and subsequent parameters. In addition, the Aggr function should be enclosed in an outer aggregation function, using the array of results from the Aggr function as input to the aggregation in which it is nested. Return data type: dual. An expression consisting of an aggregation function. By default, the aggregation function will aggregate over the set of possible records defined by the selection. StructuredParameter consists of a dimension and optionally, sorting criteria in the format: Dimension Sort-type, Ordering. The dimension is a single field and cannot be an expression. The dimension is used to determine the array of values the Aggr expression is calculated for. If sorting criteria are included, the array of values created by the Aggr function, calculated for the dimension, is sorted. This is important when the sort order affects the result of the expression the Aggr function is enclosed in. For details of how to use sorting criteria, see Adding sorting criteria to the dimension in the structured parameter. If the expression argument is preceded by the distinct qualifier or if no qualifier is used at all, each distinct combination of dimension values will generate only one return value.

DISTINCT : If the expression argument is preceded by the distinct qualifier or if no qualifier is used at all, each distinct combination of dimension values will generate only one return value, qlikview aggr. This is the normal way aggregations qlikview aggr made — each distinct combination of dimension values will render one line in the chart.

I have been looking at the documentation related to the aggr function recently and tried to use it on qs. But I find it difficult to understand it and I have a few questions about it. Does the dimension of this virtual table aggr need to be consistent with the dimension of the chart? My understanding is that the granularity of the dimensions in aggr needs to be smaller than that of the chart. Because the outside aggregation function needs to aggregate the virtual table twice.

For more generic nesting, you will have to use the advanced aggregation function in combination with calculated dimensions. An obvious question given this data would be: "How many customers does each sales representative have? The question is easily answered using a standard QlikView table:. Some new questions may arise, based on the knowledge just gained: "How may sales representatives have only a single customer? How many have three or more? If you disregard the fact that in this simple case, it is easy to count the numbers in the expression columns by hand, these are the types of questions that require a second order of aggregation. The data necessary to make the calculation does not exist in the original fields, nor can it be directly calculated from them. You need to find a way to use the expression column in the chart above as a dimension in a new chart. This can be obtained by using the advanced aggregation function. To perform the calculation of the first chart as an inner chart calculation in a new chart, you need to use the following statement for the dimension:.

StructuredParameter consists of a dimension and optionally, sorting criteria in the format: Dimension Sort-type, Ordering. The dimension is a single field and cannot be an expression.

An alternative set of records can be defined by a set analysis expression. These two dimensions must be used in the table or chart visualization. This is the normal way aggregations are made — each distinct combination of dimension values will render one line in the chart. The dimensions are specified in the second parameter and subsequent parameters. Search instead for. The dimensions are specified in the second parameter and subsequent parameters. This could be used in a KPI visualization, for example. In its basic form, the argument StructuredParameter in the Aggr function syntax is a single dimension. Graphical visualizations, such as bar charts and pie charts are common examples, but also non-graphical objects such as pivot tables are charts. We have a straight table with an order overview, in which we can see the PartnerID , how many orders they have placed, the lowest order value and the highest order value. Hi all, I have been looking at the documentation related to the aggr function recently and tried to use it on qs. These values are used as input to the Avg function to find the average value of sales, Labels Subscribe by Topic: SaaS. Load the following data as an inline load in the data load editor to create the chart expression example below.

The Aggr functions is one of the most advanced functions in the QIX engine, and it is not always easy to use.

Consenting to these technologies will allow us to process data such as browsing behavior or unique IDs on this site. If the expression argument is preceded by the nodistinct qualifier, each combination of dimension values may generate more than one return value, depending on underlying data structure. This way, you impose a sort order on the virtual table that is produced by the Aggr function. The Qlik Sense February release provides Qlik Sense business users, analytic creators, and data integrators a summary of the features and improvements available. For details of how to use sorting criteria, see Adding sorting criteria to the dimension in the structured parameter. I would try to solve aggregates within the data model itself. By default, the aggregation function will aggregate over the set of possible records defined by the selection. The dimension is used to determine the array of values the Aggr expression is calculated for. Without sorting criteria the result of the expression max aggr sum Customers -above Sum Customers , MonthYear depends on how the dimension MonthYear is sorted. As seen in the Syntax, Aggr can also use set expressions. Add the expression to the table, as a measure. Aggregate functions, but also other calculations within any Qlik Sense viz. So for each distinct value of the dimension you would like to aggregate on, it will give the result. Add the following expression to the KPI, as a measure:.
