Transformation Functions

ToChar Date and Numeric Functions

When using the ToChar function, you must use the .Net format strings. The following are some examples:

Format	Example
MM/dd/yyyy	08/26/2011
dddd, dd MMMM yyyy	Tuesday, 26 August 2011
dddd, dd MMMM yyyy h:mm tt	Tuesday, 26 August 2011 6:30 AM
MM/dd/yyyy h:mm tt	08/26/2011 6:30 AM
dddd, dd MMMM yyyy HH:mm:ss	Tuesday, 26 August 2011 06:30:07
MM/dd/yyyy HH:mm:ss	08/26/2011 06:30:07
####	1234
#.##	1.23
0.00	1.23
#,#	1,234,456
(###) ### - ####	(123) 456 - 7890

Notes:

Aggregate functions, such as Avg, cannot be used as parameters in transformation functions. To work around this, create a separate column containing output of the aggregate function and use this column as the parameter.
In functions, you must use a period (.) as a decimal separator. You cannot use a comma as a decimal separator.

Math Functions

Math functions return a numeric value based on input values supplied as arguments. Review the following for additional information:

Trending Functions

A moving average is used to indicate a trend. It detects the start of a trend and follows its progress, including reporting its reversal. Review the following for additional information:

Simple Moving Averages	Calculate the mean of a window for every case in the data set. It sums all cases in the window and divides the result by the number of cases in the window. Each data value is given equal weight in the calculation. .

MovingAverage(number, window_size, break_col)	Where number represents the number of data points, window_size represents a specific number of periods, and break_col represents an optional break column.
Weighted Moving Averages	Include multiplying factors to assign different weight to values from different periods. Usually, more recent a value, the higher it is weighted. To calculate a Weighted Moving Average Determine size of the calculation window, where n is the size of the window. Note: If the calculation window is said to be n, then the most recent data value in the window is multiplied by n, the next most recent multiplied by n-1, the value prior to that multiplied by n-2 and so on for all values in the Window. Divide the sum of the multiplied values by the sum of weights. Put Weighted Moving Average in a new a column.
MovingAverageWeighted(number, window_size)	Where number represents the number of data points, and window_size represents a specific number of periods.
MovingAverageWeighted(number, window_size, break_col)	Where number represents the number of data points, window_size represents a specific number of periods, and break_col represents an optional break column.
Exponential Moving Averages	Similar to Weighted Moving Averages, Exponential Moving Averages give more weight to recent data values, and all available data values are taken into account. Exponential Moving Averages are more accurate that other Moving Average calculations when original data values reveal rapid variability over time.
MovingAverageExponential (number, window_size)	Where number represents the number of data points, and window_size represents a specific number of periods.
MovingAverageExponential (number, window_size, break_col)	Where number represents the number of data points, window_size represents a specific number of periods, and break_col represents the column on which to perform the calculation.
Moving Diff	Moving Diff operates as a moving subtraction over a window and returns the difference between the current value and the first value in the window. Subtraction can only be performed on two numbers at a time. MovingDiff provides insight into a column’s recurring differences to alert the user to any abnormalities. This function does not calculate Weighted or Exponential averages.

Notes: If using MovingDiff in the Pivot section, you must use a column already added to the Facts pane. Use a positive integer equal to or less than the total number of rows in a column for the window_size value. Window_size value defaults to three if no value is specified and to the number of rows in the column if the value is greater than the number of rows in the column.

Use a positive integer equal to or less than the total number of rows in a column for the window_size value. Window_size value defaults to three if no value is specified and to the number of rows in the column if the value is greater than the number of rows in the column.

MovingMedian(number, window_size)	Where number (required) represents the column containing the numeric value to calculate and window_size (optional) represents how many rows to use in the calculation.
MovingMedian(number, window_size, break_col)	Where number (required) represents the column containing the numeric value to calculate, window_size (optional) represents how many rows to use in the calculation, and break_col (optional) represents the column on which to perform the calculation.
