Use FIRST()+n With this function, the set of values (6, 9, 9, 14) would be ranked (4, 2, 3, 1). and end are omitted, the entire partition is used. A Percent Difference From table calculation computes the difference between the current value and another value in the table as a percentage for each mark in the visualization. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); InterWorks uses cookies to allow us to better understand how the site is used. This function is the inverse of MODEL_QUANTILE. See Tableau Functions (Alphabetical)(Link opens in a new window). The value listed for January, 2012 is the average sales for November and December, 2011, and January, 2012. It uses simple examples to demonstrate how each calculation transforms data in a table. The default is descending. Click and drag Order Date a third time and drop it on the Rows shelf to the right of QUARTER(Order Date). For Rank table calculation, the default value is Descending. partition to the current row. Select Analysis > Create Calculated Field . Select Analysis > Create Calculated Field.
