First make sure Qlik GeoAnalytics is installed in QlikView. Separate installation instructions are available for GeoAnalytics for QlikView desktop and server.
After the installation, several GeoAnalytics extensions should be available in WebView mode in QlikView along with the default tables, pie charts and other elements from Qlik. The overall principle for GeoAnalytics for QlikView is that the map and the various layers are separated in different components. The map and the data from QlikView displays on the GeoAnalytics map component but the dimensions and measures are connected to the layer components. The layer components automatically connect to the map component and display the data on it. If there are multiple maps on the page you need to specify which one the layer belongs to.
