To get the value of a specific property on the first event across days in Mixpanel, you can use the "First Step Defined" property attribution in Funnels. Here's how you can do it:1. Create a funnel report in Mixpanel. 2. Add the event you're interested in as the first step of the funnel. 3. Apply a filter or breakdown by the property you want to analyze. 4. In the funnel chart below the query builder, click on "Step 1" and select "First Step Defined" for property attribution.By choosing "First Step Defined," Mixpanel will attribute the first property value to the whole funnel, regardless of whether the property value changes in subsequent steps. This allows you to analyze the property value from the first event across multiple days.It's important to note that "First Step Defined" is not necessarily the same as the first step of the funnel. Rather, it's the first time the property is given a non-null defined value.This method takes advantage of Mixpanel's default behavior of "forwardfilling" event properties, where properties present in early steps of a funnel are appended to later steps where they were previously absent.Mixpanel Docs: Funnels - Property AttributionIf you need to perform this analysis outside of the Funnels report, you might want to consider using Mixpanel's Query API or exporting the data to a system like BigQuery for custom analysis. However, the knowledge sources provided don't give specific information on how to do this for your particular use case.
