![]() However, by using ISFILTERED, the DAX expression operating over hierarchies must assume that the levels beyond the top-level of the hierarchy displayed in a visualization are not filtered outside of the visualization itself – that is, they should not be used in slicers, filters, or selected in other visuals. NOTE When ISINSCOPE is not available, ISFILTERED can be used as an alternative technique – this is the case in Excel up to version 2019. We use this measure as a convenient way to detect the hierarchy level in the measures described further in this pattern. The technique used in the measure is frequently used to implement a calculation depending on the current level of the hierarchy. The Product Level measure is of no use by itself. The evaluation of the active level must always start from the lowest level of the hierarchy, and move up one step at a time. Therefore, the measure must check the most restrictive filter first. Indeed, when the product is in scope, both category and subcategory are in scope too. The order of the conditions in SWITCH is relevant. The SWITCH statement detects the level by looking for the first level visible starting from the more granular one. In that case, the corresponding column has a single value visible in the filter context. VAR IsCatInScope = ISINSCOPE ( 'Product' )īy using ISINSCOPE, the three variables IsProductInScope, IsSubcatInScope, and IsCatInScope check whether each level of the hierarchy is currently being grouped by. VAR IsSubcatInScope = ISINSCOPE ( 'Product' ) YEAR OVER YAER OF GRANDTOTAL SPOTFIRE TRIALWant to try these tips and our other tricks for yourself in TIBCO Spotfire?

Please note that it is a column function and return type is string. ISOweek would be one of the available functions. YEAR OVER YAER OF GRANDTOTAL SPOTFIRE ISOIn this example, ISOweek function defined in the package is used to calculate ISO week Once the package is installed, you can either use data functions or expressions to perform the calculation. The first step requires installing the package ISOweek using TERR tools: Click here for detailed documentation about the package. One of the CRAN packages that can easily help is ISOWeek. Since this standard has been out since 1988, there are lots of pre-existing solutions for this calculation. Two simple and easy ways to perform this calculation are through data functions and expression functions. There are multiple ways to calculate ISO week in TIBCO Spotfire. A date is specified by the ISO week-numbering year in the format YYYY, a week number in the format ww prefixed by the letter ‘W’, and the weekday number, a digit d from 1 through 7, beginning with Monday and ending with Sunday. ISO week date is defined in Wikipedia as leap week calendar system. The most important purpose of this standard is to provide an unambiguous and well-defined method of representing dates and times, in order to avoid misinterpretation of numeric representations of dates and times, particularly when data transfer happens between countries with different conventions for writing numeric dates and times. It was issued by the International Organization for Standardization (ISO) and was first published in 1988. ISO is an international standard for representation of dates and times. ![]() Desk calendar with days and dates in July 2016, flip the calendar page Reading Time: 2 minutes ![]()
