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.
#Simple desktops sine how to
Use this function toįollow along with the steps below to learn how to create a number calculation. If it is not null, otherwise returns zero. If the average of the profit field is negative, then The number is zero, or 1 if the number is positive. The possible return values are -1 if the number is negative, 0 if This is not true of all databases.įor example, it is not true of Excel or Access. Where -1 rounds number to 10's, -2 rounds to 100's,Īnd so on.
Some databases, such as SQL Server, allow specification of a negative length, Omitted, number is rounded to the nearest integer. Specifies how many decimal points of precision to include in the Returns Null ifĪlso be applied to a single field in an aggregate calculation. Of the two arguments, which must be of the same type. 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 minimizes variation in the distance from the data point to the center of the bin. Hexagonal bins are an efficient and elegant option for visualizing 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 the integer part of a division operation, in which integer1 is divided by integer2. Rounds a number to the nearest integer of equal or greater value.ĬEILING(3.1415) = 4 Availability by data source: The result is in radians.Īrc tangent of two given numbers (x and y). The absolute value for all the numbers contained in the Budget Variance field. 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.
