TextCount - chart function

TextCount() is used to aggregate the number of field values that are non-numeric in each chart dimension.

Syntax:  

TextCount([{SetExpression}] [DISTINCT] [TOTAL [<fld {,fld}>]] expr)

Return data type: integer

Arguments:  

Argument Description
expr The expression or field containing the data to be measured.
SetExpression By default, the aggregation function will aggregate over the set of possible records defined by the selection. An alternative set of records can be defined by a set analysis expression.
DISTINCT If the word DISTINCT occurs before the function arguments, duplicates resulting from the evaluation of the function arguments are disregarded.
TOTAL

If the word TOTAL occurs before the function arguments, the calculation is made over all possible values given the current selections, and not just those that pertain to the current dimensional value, that is, it disregards the chart dimensions.

The TOTAL qualifier may be followed by a list of one or more field names within angle brackets <fld>. These field names should be a subset of the chart dimension variables.

See: Defining the aggregation scope

Examples and results:  

Customer Product OrderNumber UnitSales Unit Price
Astrida AA 1 4 16
Astrida AA 7 10 15
Astrida BB 4 9 1
Betacab BB 6 5 10
Betacab CC 5 2 20
Betacab DD     25
Canutility AA     15
Canutility CC     19
Divadip AA 2 4 16
Divadip DD 3   25
Example Result
TextCount([Product])

10 because all of the 10 fields in Product are text.

Note: "0" counts as a value and not an empty cell. However if a measure aggregates to 0 for a dimension that dimension will not be included in charts.
TextCount([OrderNumber]) 3, because empty cells are counted. Typically, you would use this to check that no numeric fields have been given text values.

Data used in example:

Temp:

LOAD * inline [

Customer|Product|OrderNumber|UnitSales|UnitPrice

Astrida|AA|1|4|16

Astrida|AA|7|1|15

Astrida|BB|4|9|9

Betacab|CC|6|5|10

Betacab|AA|5|2|20

Betacab|BB|||| 25

Canutility|AA|||15

Canutility|CC|||19

Divadip|CC|2|4|16

Divadip|DD|3|1|25
