上述题目的完整SQL查询应该是(基于Postgresql): -- 增加窗口函数,返回每个区域中,前一个年度的聚合值 SELECT "Region" , date_part('year', "Order Date") as year, sum("Sales"), LAG(sum("Sales")) OVER (partition by "Region" order by date_part('year', "Order Date") asc) FROM public.sale...
这样可视化就拥有了需要的各项信息:月份、盈利标签(Daily Profit KPI)、天。 4. 总额百分比 Percent of total 这个应该是最容易的一个,用到我们在LOD系列第一篇中讲到的最简单的LOD表达式:行级别LOD表达式,也就是省略了维度生命的fixed 表达式,比如说 { sum([sales]) },它会返回所有sales的总额,不管在视图中有...

The difference in roles and responsibilities for a big data analytics solution is further illustrated in Figure 3. Companies that take advantage of big data are 60% more likely than their peers to have business users that are able to tailor reports, dashboards and analytics without help from ...
差异百分比(percent difference from) 移动平均(moving average) 分片(tile) 本文所要阐述的是,Prep Builder中的表计算函数与Desktop有何不同?从而跳出“表计算必须基于聚合”的长久假设,通往更广阔的计算世界。 01—SQL窗口计算:Tableau表计算的参照点 简单的说,Tableau的核心技术VizQL,是把用户的交互转化为数据库的...
Ask Data lets you compare time periods with phrases such as "year over year" or "quarter over quarter." The results appear as difference or percent difference table calculations in workbooks you save from Ask Data. In the text box, click a difference calculation to choose other fields, aggreg...
