Create user segment excluding others

Hey @akiramiamoto ,
Afaik, currently creating a user segment from other segments via a formulaic approach isn’t possible out-of-the-box. If you think this is a valuable feature for your analysis, you can put in a feature/idea request here .

But if you just want to know the absolute event/user count resulting from that formula, you could leverage the Custom Formula feature in the event segmentation chart as follows:

where A is the event you specify and A1, A2 , A3 are the user segments you want to analyze that event on.

Also, there is a set intersection feature for behavioral cohorts which allows you to create a cohort from common users between 2 different cohorts if that is something which you might be interested in.

Let me know if I have interpreted your question correctly. Hope this helps!

I’ve wanted to do something similar occasionally myself, but as @Saish Redkar says, this isn’t currently possible.

I’ll throw in two more suggestions:

1. If you are going to use cohort C a lot, you can create it by adding the conditions you have for A and B as negatives. I.e. HAS NOT performed event a, HAS NOT had user property value b.
2. If this is a one-off, while setting up a chart you can create a segment, add a condition Cohort, choose both A and B cohorts, and then click on the = symbol in front of the cohorts to change it to ≠ instead.

Thanks for the answers @Saish Redkar and @MikkoKarvonen !
