Question

我要求制作一个缺陷的mtd pareto。我需要4列：item，qty，share％和defect％。缺陷％应该是累积百分比。很感谢任何形式的帮助。谢谢。

defect% = itemqty/total volume qty
share%  = itemqty/total defect qty

（我想总结当前行的份额+上一行的份额。）

total defect itemqty  16
total volume itemqty  13

样品： item itemqty total volume qty

hardware  7 /16
Locked    5/16+sharepct of hardware
corroded  4/16+sharepct of locked

下面是一个示例数据：

month       model  item       itemqty volumeqty
===============================================
2016(1) Jan  P6   Locked         1      1
2016(1) Jan  P6   Locked         1      0
2016(1) Jan  P6   Locked         1      1
2016(1) Jan  P6   Locked         1      1
2016(1) Jan  P5   Locked         1      1
2016(1) Jan  P6   hardware       1      1
2016(1) Jan  P6   hardware       1      0
2016(1) Jan  P6   hardware       1      1
2016(1) Jan  P6   hardware       1      1
2016(1) Jan  P5   hardware       1      1
2016(1) Jan  P5   hardware       1      0
2016(1) Jan  P5   hardware       1      1
2016(1) Jan  P6   corroded       1      1
2016(1) Jan  P6   corroded       1      1
2016(1) Jan  P6   corroded       1      1
2016(1) Jan  P5   corroded       1      1

一个非常相似的主题讨论累积总和和百分比：

Spotfire Custom Expression : Calculate (Num/Den) Percentages

你想要使用类似的东西：

Sum(If(trim([model])="P6",[itemqty])) then Sum([Value]) over (AllPrevious([Axis.Rows]))

在Spotfire中运行百分比
