# Funnel The central metaphor for all marketing is the funnel: the narrowing cohorts of users as they pass from initial action to eventual sale. Spindl lets you easily plot arbitrary events by filtering and ordering them on the left-hand picker, as you do almost everything in [ChartBuilder](https://docs.spindl.xyz/spindl/features/web3-native-analytics/chartbuilder). Careful! The funnel is necessarily a decaying number of events or users: counts in the rightmost buckets *only* appear if a user passed through the events to the left. Meaning, the total in *token received* below is only the tokens received by people who started the funnel in 'page views from Twitter users' on the left.
