How do I see a map showing from where my audience is?

The real time map showing your current audience, and a regular map showing where your users came from at a particular date and date range, are both available in the Media menu in your analytics dashboard. The map displays your users by continent, country and you can go down to particular regions and cities. To use this feature make sure Geolocation is set up correctly in your Matomo Analytics (formerly Piwik Analytics).
