Use this interactive demo to learn how to annotate data points on a Mixpanel line chart.

Quick summary

Mixpanel annotations let you mark specific data points on a line chart with timestamped notes, making it easy to correlate metric changes with real-world events. This feature helps product and analytics teams add context directly inside their reports without leaving the platform.

Steps

Open a report in Mixpanel by clicking on its header space.
Hover your cursor over the line chart to reveal a marker on the graph and a (+) icon below it indicating the exact point you can annotate.
Click the (+) icon to open the Add Annotation dialog.
Enter your annotation text and a timestamp, then click Save.
View your saved annotations by clicking the annotated point, which displays a count of all notes added to that data point.

📌 Why this matters

Mixpanel annotations allow product managers and data analysts to attach timestamped notes directly to line chart data points, providing instant context for metric spikes or drops. This eliminates the guesswork of correlating analytics changes with product releases, marketing campaigns, or incidents. By surfacing explanations inside the report itself, teams can make faster, better-informed decisions without switching between tools. Annotations are a critical feature for any team that needs shared, auditable context around their product analytics data.
