[英]Tableau using field quarterly record with monthly data
My goal is to create a monthly employment data series given that each record has the following fields: year, quarter, and 3 monthly fields of the actual data (month 1 employment, month 2 employment, and month 3 employment).我的目标是创建一个月度就业数据系列,因为每个记录都有以下字段:实际数据的年、季度和 3 个月度字段(第 1 个月的就业、第 2 个月的就业和第 3 个月的就业)。 I have to associate each month of data to an actual month (eg, month 2 of quarter 3 in 2018 as employment for August 2018).
我必须将每个月的数据与实际月份相关联(例如,2018 年第 3 季度的第 2 个月作为 2018 年 8 月的就业)。 Each record represents a firm.
每条记录代表一个公司。 A firm will have records associated with each month.
公司将有与每个月相关的记录。 So, looking for total employment.
所以,寻找总就业。 There are multiple quarters and multiple years.
有多个季度和多年。 Would I have to restructure the data or create a calculation?
我是否必须重组数据或创建计算? Any suggestions?
有什么建议?
This can be done using 'calculated field' easily.这可以使用“计算字段”轻松完成。 Assuming your three fields are
year
, quarter
and month
respectively, you can create my_month
as follows.假设您的三个字段分别是
year
、 quarter
和month
,您可以按如下方式创建my_month
。
sample data input样本数据输入
year, quarter, month
2018, 1, 1
2018, 2, 1
2019, 4, 3
calculated field my_date
as计算字段
my_date
为
MAKEDATE([Year], ([Quarter]-1)*3+[Month], 1)
Thereafter add calculated field Total_emp_each_month
as此后添加计算字段
Total_emp_each_month
作为
{
Fixed [my_date] : sum([employment])
}
