选择不同的CourseName,度量值Speaker#自动根据Filter做相应的数据过滤,重新统计数据,这种过滤的流向是单向的,由数据关系中的交叉过滤方向(Cross Filter Direction)决定,PowerBI允许在不修改关系的情况下,编辑Filter和度量值的交互行为,使报表中的不同图表(Visiualization)选择性地响应或不响应过滤条件(Filter)。 1,选择F...
在PowerBI中,关系(Relationship)是指数据表之间的基数(Cardinality)和交叉筛选方向(Cross Filter Direction)。 我的PowerBI开发系列的文章目录:PowerBI开发 基数(Cardinality) 基数关系类似于关系表的外键引用,都是通过两个数据表之间的单个数据列进行关联,该数据列叫做查找列,两个数据表之间的基数关系是...
在PowerBI Desktop的关系(Relationship)视图中,通过实线/虚线表示物理关系(Physical Relationship),实线的两端是1和*号,表示关系的两端,这种实线表示的关系处于活跃状态,虚线是不活跃的关系。虚拟关系(Virtual Relationship)是通过DAX表达式(例如,通过FILTER函数)创建的关系,一般是用在度量值中,用于交互查询。PowerBI的关系...
当关系的“Cross Filter Direction”属性设置为双向的箭头,即把Cross Filter Direction设置为Both时,为了实现数据的过滤,逻辑上可以认为,PowerBI把这两个表展开成一个大表。 双向交叉过滤方向会导致有些关系处于不活跃状态(inactive),当一个维度(lookup)表和多个事实表有关系时,避免使用Both方向,这样可能会导致部分关系...

In Power BI Desktop model view, you can interpret a relationship's cross filter direction by noticing the arrowhead(s) along the relationship line. A single arrowhead represents a single-direction filter in the direction of the arrowhead; a double arrowhead represents a bi-directional relationship....
By default, Power BI Desktop automatically configures the options Cardinality (direction), Cross filter direction, and Make this relationship active for your new relationship. However, you can change these settings if necessary. For more information, see Understanding additional options....
