NumericCount - chart function
NumericCount() aggregates the number of numeric values in each chart dimension.
Syntax:
NumericCount({[SetExpression] [DISTINCT] [TOTAL [<fld {,fld}>]]} expr)
Return data type: integer
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. By using TOTAL [<fld {.fld}>], where the TOTAL qualifier is followed by a list of one or more field names as a subset of the chart dimension variables, you create a subset of the total possible values. |
Example | Result |
---|---|
NumericCount(OrderNumber) |
Returns the number of rows in the OrderNumber field that have numeric values.
Information 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. Empty cells are evaluated as non-numeric values and are not counted by NumericCount. |
NumericCount(Product) | Returns the number of product names that are numeric values. Typically you might use this to check that no text fields have been given numeric content. |
NumericCount (DISTINCT OrderNumber)/Count(DISTINCT OrderNumber) | Counts the number of distinct numeric order numbers and divides it by the number of order numbers, numeric and non-numeric. This will be 1 if all field values are numeric. |
