计算列中出现的次数

Question

我对不同群体的成员（例如第1组至第4组）进行了调查，了解他们是否同意或不同意某些内容。我试图在Microsoft PowerBI Desktop中绘制这些响应。

我加载了一个数据模型，在单个表中包含这些列：

Group    Question1   Question2
Group1   Agree       Agree
Group1   Disagree    Agree
Group4   Disagree    Disagree
Group3   Agree       Agree
Group2   Disagree    Agree
Group2   Agree       Disagree
Group4   Agree       Agree
Group1   Agree       Disagree

我想知道是否有一个可以计算单词出现次数的DAX＆＃34;同意＆＃34;和＆＃34;不同意＆＃34;这样我可以将它们作为堆积条形图上的值（每个问题一个图表）：

Group1   Agree---------   Disagree----
Group2   Agree-------  Disagree-------
Group3   Agree----------  Disagree----
Group4   Agree------  Disagree--------

（为ASCII艺术道歉）

我尝试过使用COUNTA（）函数，但它只是保持返回行数。我还尝试将问题列作为数据字段拖动，但又一次，只是使每个条的长度相同，因为它们的总响应数相同。

提前致谢。

Answer 1

您需要将您的桌子取消 - 以获得如下结构：

Group  |  Question  |  Answer
Group1 |  Question1 |  Agree
Group1 |  Question2 |  Disagree
...

您的措施如下所示：

RowCount:= COUNTROWS(FactAnswer)

AgreeCount:=
CALCULATE(
    [RowCount]
    ,FactAnswer[Answer] = "Agree"
)

DisagreeCount:=
CALCULATE(
    [RowCount]
    ,FactAnswer[Answer] = "Disagree"
)

Answer 2

我们需要创建六个度量（清晰和简化）

1）Agree Q1 = CALCULATE(COUNTA(SO_table[Question1]),SO_table[Question1]="Agree")

2）Agree Q2 = CALCULATE(COUNTA(SO_table[Question2]),SO_table[Question1]="Agree")

3）Disagree Q1 = CALCULATE(COUNTA(SO_table[Question1]),SO_table[Question1]="Disagree")

4）Disagree Q2 = CALCULATE(COUNTA(SO_table[Question2]),SO_table[Question1]="Disagree")

5）Total Agree = Agree Q1 + Agree Q2

6）Total Disagree = Disagree Q1 + Disagree Q2

然后，您可以使用堆积条并绘制Total Agree＆amp; Total Disagree

Answer 3

您可以使用以下DAX表达式为每个问题创建一个表：

Table = SUMMARIZE('YourTable',YourTable[Group],"Agree",
COUNTAX(FILTER('YourTable',YourTable[Question1]="Agree"),
YuorTable[Question1]),"Disagree",
COUNTAX(FILTER('YourTable',YourTable[Question1]="Disagree"),YourTable[Question1]))

示例：

YourTable

对于Question1，您将获得下表：

获得表后，只需创建所需的图表。

如果这有用，请告诉我。
