Hey Flor!

Amplitude is an event-based analytics platform. For each event, user and event properties are sent in. For this user property of “# of dreams created”, I see that one user can have events with different values. 

If you use User Composition chart, and query for “# of dreams created”, and select “cross-property values”, you will see a breakdown of users with more than one value for this property:

If you click into a user with two values e.g. 0 and 1, let’s take this user for example: https://analytics.amplitude.com/Dreamfora0205/project/303550/search/amplitude_id%3D227034653565

If you look at the event “Sleep App”, user property “# of dreams created” = 1

However, if you look at the event “Click Setting”, user property “# of dreams created” = 0

Both of these events took place on 21 July.

This means that when you create a cohort or a chart that looks for users grouped by user property “# of dreams created” in the last 30 days for example, this user will appear in both the “0” and “1” buckets.

Hi Ning.chang

Wow, actually that was really helpful.

Thank you so much for your kind explanation!

This helped me much more how the user composition chart works!

I didn’t notice that this chart default setting is for ‘Most Recent Value’,

and there are more options for this.

Thanks a lot!!

with best regards, Flor Cho
