| Name | Description |
|---|---|
Avg
|
Calculates the average of all the values within the specified summary region (group, page or report). |
Count
|
Counts the number of values within the specified summary region (group, page or report). |
Sum
|
Calculates the total of all the values within the specified summary region (group, page or report). |
RunningSum
|
Summarizes all the values, which were printed before the current data row, with the current data row’s value. |
CarryoverSum
|
Summarizes all the values before the current position and calculates the carried forward and brought forward totals. |
Percentage
|
Calculates the percent ratio of the current data row’s value to the total of all the values within the specified summary region (group, page or report). |
Max
|
Calculates the maximum of all the values within the specified summary region (group, page or report). |
Min
|
Calculates the minimum of all the values within the specified summary region (group, page or report). |
Median
|
Finds the middle number within a sequence. Note that if the total number of elements is odd, this function returns the value of a middle number in a sequence. If the total number of elements is even, this function returns the arithmetical mean of the two middle numbers. |
Var
|
Calculates the amount of variance for all the values within the specified summary region (group, page or report). |
VarP
|
Calculates the population variance of all the values within the specified summary region (group, page or report). |
StdDev
|
Calculates the standard deviation of all the values within the specified summary region (group, page or report). |
StdDevP
|
Calculates the standard population deviation of all the values within the specified summary region (group, page or report). |
DAvg
|
Calculates the average of all the distinct values within the specified summary region (group, page or report). |
DCount
|
Counts the number of distinct values within the specified summary region (group, page or report). |
DSum
|
Calculates the total of all the distinct values within the specified summary region (group, page or report). |
DVar
|
Calculates the amount of variance for all the distinct values within the specified summary region (group, page or report). |
DVarP
|
Calculates the population variance of all the distinct values within the specified summary region (group, page or report). |
DStdDev
|
Calculates the standard deviation of all the distinct values within the specified summary region (group, page or report). |
DStdDevP
|
Calculates the standard population deviation of all the distinct values within the specified summary region (group, page or report). |
RecordNumber
|
Returns the current record number in the data source within the specified summary region (group, page or report). This means for instance, if the summary is calculated for a group, then the record number is calculated only within that group, and is reset every time a new group is started. |
Custom
|
Calculates the custom summary using the XRLabel.SummaryReset, XRLabel.SummaryRowChanged and XRLabel.SummaryGetResult events. |
Remarks
This enumeration is used by the XRSummary.Func property.
