When subcategory is brought into the view, the minimum sales for each subcategory are shown.The apps included in the list below all offer free trial versions. This example shows the minimum sales per category. When Minimum Sales is placed on Text on the Marks card in the worksheet, its name is changed to AGG(Minimum Sales), which indicates that it cannot be aggregated any further, since it is already aggregated down to the lowest level of detail (the smallest sales value for all records). Just like your other fields, you can use it in one or more visualisations. The new number calculation appears under Measures in the Data pane. Name the calculated field Minimum Sales transaction In the calculation editor that opens, do the following: Navigate to a worksheet and select Analysis > Create Calculated Field. In Tableau Desktop, connect to the Sample - Superstore saved data source, which comes with Tableau.

Use this function to use zero values instead of null values.įollow along with the steps below to learn how to create a number calculation. Returns the expression if it is not null, otherwise returns zero. If the average of the profit field is negative, then Returns the sign of a number: The possible return values are -1 if the number is negative, 0 if the number is zero, or 1 if the number is positive. For example, it is not true of Excel or Access. Some databases, such as SQL Server, allow specification of a negative length, where -1 rounds number to 10's, -2 rounds to 100's and so on. This example rounds every Sales value to an integer: If decimals is omitted, number is rounded to the nearest integer. The decimals argument specifies how many decimal points of precision to include in the final result. Rounds numbers to a specified number of digits. Raises the number to the specified power.Ĭonverts the given number from degrees to radians. Returns the numeric constant pi: 3.14159. MIN can also be applied to a single field in an aggregate calculation. Returns the minimum of the two arguments, which must be of the same type. MAX can also be applied to a single field in an aggregate calculation. Returns the maximum of the two arguments, which must be of the same type. If the base value is omitted, base 10 is used. Returns the logarithm of a number for the given base. Returns Null if number is less than or equal to 0. Returns the natural logarithm of a number. The bins have side length 1, so the inputs may need to be scaled appropriately. Maps an x, y coordinate to the y-coordinate of the nearest hexagonal bin. This makes the clustering both more accurate and informative. Because the bins are hexagonal, each bin closely approximates a circle and minimises variation in the distance from the data point to the centre of the bin. Hexagonal bins are an efficient and elegant option for visualising data in an x/y plane such as a map. HEXBINX and HEXBINY are binning and plotting functions for hexagonal bins. Maps an x, y coordinate to the x-coordinate of the nearest hexagonal bin. Rounds a number to the nearest integer of equal or lesser value.įLOOR(3.1415) = 3 Availability by data source: Returns e raised to the power of the given number. Returns the integer part of a division operation, in which integer1 is divided by integer2.

Specify the angle in radians.Ĭonverts a given number in radians to degrees. Rounds a number to the nearest integer of equal or greater value.ĬEILING(3.1415) = 4 Availability by data source: Returns the arc tangent of two given numbers (x and y). Returns the arc tangent of a given number. Returns the arc cosine of the given number. The second example returns the absolute value for all the numbers contained in the Budget Variance field. Returns the absolute value of the given number. Number functions available in Tableau Function The calculation might look something like this: You can use the ABS function to return the absolute value of that number, and all the other numbers in that field. For more information, see Data Types.įor example, you might have a field that contains values for the variance in your budget, titled Budget Variance. Number functions can only be used with fields that contain numerical values. Number functions allow you to perform computations on the data values in your fields. It also demonstrates how to create a number calculation using an example. This article introduces number functions and their uses in Tableau.
