PowerBI DAX 表达式: 这看似一种递归的效果,但其实可以转化为非递归实现,在 Tableau 和 PowerBI 两者中都并非真正的递归,在 PowerBI DAX 中是不支持真正递归的,当然在这种案例中也不用使用真正的递归。 小结: - PowerBI DAX 计算可以非常容易地实现效果。 加权平均 对于考试分数或订单优先级等数据,适合采用加权...
Users who are new to Power BI Desktop can use this article as a quick and easy introduction on how you can use Data Analysis Expressions (DAX) to solve many basic calculations and data analysis problems. We’ll go over some conceptual information, a series of tasks you can complete, and ...

在PowerBI 中,模拟类似的需求,效果如下: 首先构建一个用来分组的辅助表作为图例,然后编写 PowerBI DAX 表达式如下: 小结: PowerBI DAX 计算可以非常容易地实现效果。 PowerBI 中为了报表层效果有时候需要建立辅助报表层的辅助表,这是不符合设计常识的,PowerBI 有独立的模型层,里面的表反应了实际的业务,而不应该将...
This learning path introduces Data Analysis Expressions (DAX) and provides you with foundational skills required to enhance semantic models with calculations. It starts by describing Power BI Desktop model structure and how it can be enhanced with DAX calculations. It then describes how you can ...
functions and operations for implementing custom calculations in Power BI. It is also called a function language since the customizable parameters are defined inside a specific DAX function. With DAX functions, you can solve high-end calculations, data analysis problems, and complex Power BI tasks....
