Question

我试图了解DAX如何转换数据以及如何使用它来让我在Power BI中紧凑地显示一些数据。

我的Regional Sales Performance数据看起来像这样：

+---------------+----------------------+----------------------+-------------------+------------------+-----+
| Sales Month   | Northeast Calls Made | Northeast Sales Made | Northeast Revenue | South Calls Made | ... |
+---------------+----------------------+----------------------+-------------------+------------------+-----+
| February 2017 |                   15 |                   13 |           3000.00 |               12 | ... |
+---------------+----------------------+----------------------+-------------------+------------------+-----+
| March 2017    |                   21 |                    9 |           2000.00 |               30 | ... |
+---------------+----------------------+----------------------+-------------------+------------------+-----+
| April 2017    |                    5 |                    5 |           1000.00 |               18 | ... |
+---------------+----------------------+----------------------+-------------------+------------------+-----+

最终，在过滤掉我的数据后（例如Sales Month = "February 2017"），我希望显示如下：

+------------+-----------+-------+---------+------+
|            | Northeast | South | Midwest | West |
+------------+-----------+-------+---------+------+
| Calls Made |        15 |    12 |     ... |  ... |
+------------+-----------+-------+---------+------+
| Sales Made |        13 |   ... |     ... |  ... |
+------------+-----------+-------+---------+------+
| Revenue    |   3000.00 |   ... |     ... |  ... |
+------------+-----------+-------+---------+------+

由于我有一组已知的静态区域，我最好的猜测是创建一个DAX语句，每个区域有一个ROW()联合在一起：

UNION(
    ROW("Region", "Northeast", "Key", "Revenue", "Value", SUM('My Input')[Northeast Revenue], ...),
    ROW("Region", "Northeast", "Key", "Sales",   "Value", SUM('My Input')[Northeast Sales Made], ...),

    ROW("Region", "South",     "Key", "Revenue", "Value", SUM('My Input')[South Revenue], ...),
    ROW("Region", "South",     "Key", "Sales",   "Value", SUM('My Input')[South Sales Made], ...),

    ROW("Region", "Midwest",   "Key", "Revenue", "Value", SUM('My Input')[Midwest Revenue], ...),
    ROW("Region", "Midwest",   "Key", "Sales",   "Value", SUM('My Input')[Midwest Sales Made], ...)
)

这或多或少有效，但看起来非常单一，并且它不会保留列类型。例如，电话和销售是整数;收入是固定宽度的小数;其他列可能是百分比。

有更好的方法吗？

Answer 1

是的，有！有＆＃39; unpivot＆＃39;查询编辑器的“变换”选项卡中的选项。在那里，您可以取消数据。

我已经使用您的数据创建了一个示例：

取消透视列
分裂区域＆amp;输入
拆分月份＆amp;年（尽管您可以使用PowerBI内置数据功能）

链接到PBIX，因此您可以看到我在查询编辑器中执行的步骤。 Link
