Spotfire计算自“另一列中的条件”以来的天数

Question

I have a [Date] column and a [STATUS] column. [Status] can be either "Up" or "Down". I want to count the number of days [STATUS]="Down"

date          status     new_calculated_column
1/1/2001      up         0
1/2/2001      down       1
1/3/2001      up         0

Any suggestions?

Answer 1

This will work using SUM or COUNT

SUM(IF([STATUS] = "Down",1,0))

or....

COUNT(IF([STATUS] = "Down",1,0))
