Milestones are a simple way to add past achievements or upcoming targets to all of your metrics in Notion.
By annotating your charts, you can now see how the actions your company is taking can affect your numbers.
To create a milestone, find the link in the left sidebar under the Account section.
Next, you'll want to add a date and a text description.
It's that easy.
Milestones are indicated with a flag when viewing your dashboards or metric show pages. By hovering over an interval with a milestone, you'll see the date and description added to the tooltip.
