Tableau – Operators

 

 – Arithmetic , Relational and Logical Operators

Tableau is a data visualization software that allows users to create interactive dashboards and reports

An Operators are symbols that instruct the compiler to carry out a specific mathematical or logical operation. Calculated fields and formulas can be created using Tableau’s operators.

Types of Tableau Operators

There are 3 basic operators in tableau:

  • Arithmetic Operators
  • Relational Operators
  • Logical Operators

Arithmetic Tableau Operators

Tableau supports the basic arithmetic operators such as addition (+), subtraction (-), multiplication (*), and division (/). These operators can be used to perform mathematical calculations on fields and create new fields based on those calculations.

Relational Operators

In Tableau, relational operators are used to compare values and determine if they meet certain conditions. These operators include:

  • Equals (=): This operator is used to compare two values and check if they are equal to each other.
  • Not Equals (<>): This operator is used to compare two values and check if they are not equal to each other.
  • Greater Than (>): This operator is used to compare two values and check if the first value is greater than the second value.
  • Greater Than or Equal To (>=): This operator is used to compare two values and check if the first value is greater than or equal to the second value.
  • Less Than (<): This operator is used to compare two values and check if the first value is less than the second value.
  • Less Than or Equal To (<=): This operator is used to compare two values and check if the first value is less than or equal to the second value.

These operators can be used in Tableau calculations to filter data, create conditional formatting, and create calculated fields. For example, if you want to filter your data to show only sales that are greater than $100, you can use the Greater Than operator in a filter condition.

A comparison/relational operator is a binary operator that compares the values of two operands. In conditional statements, especially in loops, comparison operators determine whether execution should proceed based on the result of the comparison. Conditional processing is the key to program flow control.

Logical Operators

Tableau supports several logical operators, including AND, OR, and NOT. Logical operators are used to create complex Boolean expressions in Tableau that can be used in filters, calculations, and other parts of the software.

The AND operator returns TRUE if both expressions being evaluated are TRUE. For example, if you have two filters, one filtering data by region and another by date, you can use the AND operator to show data only for a specific region and a specific date.

The OR operator returns TRUE if at least one of the expressions being evaluated is TRUE. For example, if you want to show data for either a specific region or a specific date, you can use the OR operator.

The NOT operator returns the opposite Boolean value of the expression being evaluated. For example, if you have a filter that shows data for a specific region, you can use the NOT operator to exclude that region from the results.

In addition to these three logical operators, Tableau also supports the IF-THEN-ELSE statement, which can be used to create more complex logical expressions. The IF-THEN-ELSE statement evaluates a condition and returns one value if the condition is true and another value if the condition is false.

Using logical operators in Tableau can help users to create more precise filters and calculations, and to gain deeper insights into their data.

Conclusion

These operators will help us work with Tableau better and do our work more efficiently.
