Spotfire如何沿一個顏色計算

Question

我有一個數據表，如下所示。我想創建一個名爲「Time Difference」的新列，它捕獲[STAGE]開始和[STAGE]結束之間的時間差。有沒有辦法做到這一點，而不使用數據轉換？

謝謝！

假設每個ID是獨一無二的，你的數據是由Time有序其中Stage = Start是第一排的每個ID和Stage = End是最後一排的每個ID，您可以使用此：

Concatenate(Min([Time]) OVER ([ID]),"-",Max([Time]) over ([ID])) 

成績

+----+---------+---------+------+-----------------+ 
| ID | Stage | Action | Time | Time Difference | 
+----+---------+---------+------+-----------------+ 
| 1 | Start | approve | A | A-F    | 
| 1 | Process | approve | B | A-F    | 
| 1 | Process | approve | C | A-F    | 
| 1 | Process | approve | D | A-F    | 
| 1 | Process | decline | E | A-F    | 
| 1 | End  | approve | F | A-F    | 
| 2 | Start | approve | G | G-I    | 
| 2 | Process | decline | H | G-I    | 
| 2 | End  | approve | I | G-I    | 
+----+---------+---------+------+-----------------+ 

如果您的數據尚未排序，你可以申請一個Rank()來解決這個問題。讓我知道如果是這樣的話。

用新數據

表達

Concatenate(Min(If((Upper([Stage])="START") and (Upper([Action])="APPROVE"),Max([Time]) OVER ([ID]))) OVER ([ID]),"-",Min(If((Upper([Stage])="END") and (Upper([Action])="APPROVE"),Max([Time]) OVER ([ID]))) OVER ([ID])) 

簡化EDIT

Concatenate(Min(If((Upper([Stage])="START") and (Upper([Action])="APPROVE"),[Time])) OVER ([ID]),"-",Min(If((Upper([Stage])="END") and (Upper([Action])="APPROVE"),[Time])) OVER ([ID])) 

個結果

+----+---------+---------+------+-----------------+ 
| ID | Stage | Action | Time | Time Difference | 
+----+---------+---------+------+-----------------+ 
| 1 | On hold | decline | A | C-H    | 
| 1 | Start | decline | B | C-H    | 
| 1 | Start | approve | C | C-H    | 
| 1 | Process | DECLINE | D | C-H    | 
| 1 | Process | approve | E | C-H    | 
| 1 | Process | approve | F | C-H    | 
| 1 | End  | decline | G | C-H    | 
| 1 | End  | approve | H | C-H    | 
| 2 | Start | approve | I | I-K    | 
| 2 | Process | decline | J | I-K    | 
| 2 | End  | approve | K | I-K    | 
+----+---------+---------+------+-----------------+
