What are the calculation functions in Tableau?
Tableau course in Chandigarh Its provides a wide range of calculation functions that allow users to create custom calculations, perform data transformations, and derive new insights from their data. These functions can be used in calculated fields, calculated table calculations, and calculated measures. Here are some of the key calculation functions in Tableau:
SUM(): Calculates the sum of a numeric field.
AVG(): Computes the average of a numeric field.
MIN(): Determines the minimum value in a field.
MAX(): Identifies the maximum value in a field.
COUNT(): Counts the number of non-null values in a field.
MEDIAN(): Calculates the median of a field.
STDEV() or STDEVP(): Computes the standard deviation of a field (sample or population).
Date and Time Functions
TODAY(): Returns the current date.
NOW(): Returns the current date and time.
DATEADD(): Adds a specified interval to a date.
DATEDIFF(): Calculates the difference between two dates.
DATEPART(): Extracts specific components (e.g., year, month) from a date.
CONCATENATE(): Combines two or more strings.
LEFT(): Retrieves a specified number of characters from the beginning of a string.
RIGHT(): Retrieves a specified number of characters from the end of a string.LEN(): Calculates the length (number of characters) of a string.
UPPER(): Converts a string to uppercase.
LOWER(): Converts a string to lowercase.
TRIM(): Removes leading and trailing spaces from a string.
REPLACE(): Replaces one substring with another within a string.
IF(): Performs conditional logic and returns one of two specified values based on a condition.
AND(): Checks if multiple conditions are true.
OR(): Checks if at least one of multiple conditions is true.
NOT(): Negates a Boolean value.
WINDOW_SUM(): Calculates a running sum of a measure within a specified window of data.
WINDOW_AVG(): Computes a running average of a measure within a specified window of data.
WINDOW_MAX(): Finds the maximum value of a measure within a specified window of data.
WINDOW_MIN(): Finds the minimum value of a measure within a specified window of data.
Table Calculation Functions
RUNNING_SUM(): Computes a running sum of a measure across a table calculation.
RUNNING_AVG(): Calculates a running average of a measure across a table calculation.
RANK(): Assigns a rank to values based on a specified order.
LOOKUP(): Retrieves the value of a field from a previous or subsequent row.
Level of Detail (LOD) Functions
INCLUDE Level of Detail (INCLUDE LOD): Performs calculations at a specified level of detail.
EXCLUDE Level of Detail (EXCLUDE LOD): Excludes a specified dimension from the level of detail of the calculation.
FIXED Level of Detail (FIXED LOD): Defines a fixed level of detail for the calculation.
ISNULL(): Checks if a value is null.
ZN(): Converts null values to zeros.
IFNULL(): Returns the first non-null value in a list of expressions.
SCRIPT_REAL(): Allows you to use R or Python scripts for calculations.
These are just some of the calculation functions available in Tableau. Depending on your specific analysis and reporting needs, you can use these functions to create custom calculations that help you gain deeper insights from your data and build more informative visualizations.
