The CALCULATE function in DAX is the magic key for many calculations we can do in DAX. However...
得到一个数据集合,并利用第一个参数执行聚合运算,这不就是DAX要实现的功能:提取有用数据并执行聚合运算吗,所以说CALCULATE几乎就是DAX本身,它就是实现DAX功能的引擎,并能灵活的操控外部上下文,后面的数据分析也都离不开CALCULATE的身影。
In Power BI, there is a common combination of DAX functions that allow us to create a dynamic cumulative total on any report page. And the key DAX function here is CALCULATE. Once you understand how CALCULATE works in this formula pattern, you’ll understand the logic for ...

A visual can then be used in Power BI to show the Total NPS measure that was created. In the following example, a custom tachometer gauge visual can be used to provide clear and accurate analysis of the NPS score. To achieve this task, set the start value of the axis to-100and set...
This month, we are continuing our work on the ongoing previews of DirectQuery for PowerBI datasets and Azure Analysis Services, Small Multiples, and the Model View UI. Also, we are making it easier to specify filters in the DAX CALCULATE function. On the Service side, when you click on a...
《DAX神功》第1卷第21回 我们讲到 all有多个功能,其中它可以是calculate的调节器,也可以是表。在calculate中做参数时它是调节器(取消筛选功能),但是在filter中它只是表而已! 证明如下:是否使用all(表) 与在Filter中筛选这张表无关,因为all(表)还是返回这张表,不影响filter的筛选,他在filter中不是取消筛选的功能...
