Tableau api 如何基于多个下拉列表中选定的尺寸创建视图

我想创建一个单一视图，根据每个学科的及格/不及格分数，根据性别和年龄给出学生总数

下面是我的模式和数据集

 (id,name,age,Gender,english_grade,Mathematics_grade,Physics_grade,chemistry_grade,grade_ind)

   100  Steve   14  MALE    PASS    PASS    PASS    PASS    Y
   101  Edward  15  MALE    PASS    FAIL    PASS    PASS    Y
   102  Andy    15  FEMALE  PASS    FAIL    PASS    PASS    Y
   103  Kim     16  FEMALE  PASS    FAIL    PASS    PASS    Y
   104  Tammy   14  FEMALE  PASS    FAIL    PASS    PASS    Y
   105  Sue     15  FEMALE  PASS    FAIL    PASS    PASS    Y
   106  Chen    15  MALE    PASS    FAIL    PASS    PASS    Y
   107  Kim     16  FEMALE  PASS    FAIL    PASS    PASS    Y
   108  Jim     14  MALE    PASS    FAIL    PASS    PASS    Y
   109  Annie   15  FEMALE  PASS    FAIL    PASS    PASS    Y
   110  Anna    15  FEMALE  PASS    FAIL    PASS    PASS    Y
   111  Royce   16  MALE    PASS    FAIL    PASS    PASS    Y
   112  Mike    14  MALE    PASS    FAIL    PASS    PASS    Y
   113  Peter   15  MALE    FAIL    FAIL    PASS    PASS    Y
   114  Board   15  MALE    FAIL    FAIL    PASS    PASS    Y
   115  Andrew  16  MALE    FAIL    FAIL    FAIL    FAIL    N
   116  William 14  MALE    FAIL    FAIL    FAIL    FAIL    N
   117  Santa   15  MALE    FAIL    FAIL    FAIL    FAIL    N
   118  Sandy   15  MALE    FAIL    FAIL    FAIL    FAIL    N
   119  Danny   16  MALE    FAIL    FAIL    FAIL    FAIL    N
   120  Melisa  14  FEMALE  FAIL    FAIL    FAIL    FAIL    N
   121  Merlin  15  FEMALE  FAIL    FAIL    FAIL    FAIL    N
   122  Betsy   15  FEMALE  FAIL    FAIL    FAIL    FAIL    N
   123  Bill    16  MALE    FAIL    FAIL    FAIL    FAIL    N

我使用参数创建了4个下拉列表，但不知道如何为这些参数应用计算字段

因此，现在根据以上选择，我想要一个观点，根据性别，给出化学、英语和物理及格但数学不及格的学生总数

基本上我想应用一个计算作为

 IF(chemistry = 'PASS' AND English ='PASS' AND Physics = 'PASS' AND Maths ='FAIL')

同样地，根据这4个下拉列表中的每个选择，我希望反映我的观点

其他一些可能的选择包括

  IF(chemistry = 'PASS' AND English ='FAIL' AND Physics = 'FAIL' AND Maths ='FAIL')

 IF(chemistry = 'FAIL' AND English ='PASS' AND Physics = 'PASS' AND Maths ='FAIL')

 IF(chemistry = 'PASS' AND English ='PASS' AND Physics = 'PASS' AND Maths ='PASS')

我尝试了下面的计算字段，但它没有显示正确的视图

CASE [chemistry]
WHEN 'PASS' then [Chemistry Grade]
WHEN 'FAIL' then [Chemistry Grade]
ELSE ''
END

非常感谢您的帮助……

您可以尝试将其转换为一个总数，而不是计数。尝试以下方法作为起点：

SUM(IF(chemistry = 'PASS' AND English ='PASS' AND Physics = 'PASS' AND Maths ='FAIL') THEN 1 ELSE 0 END)
