Map: Marker Charts
Map marker charts are supported by all Zoomdata data connectors, however the data for map marker charts must contain latitude and longitude fields. Zoomdata supports a variety of tile providers which offer an overlay design for the map visualization styles available in the program. These include: OpenStreetMap, OpenMapSurfer, MapQuest, CloudMade, and MapBox. MapQuest, CloudMade and MapBox require an API key.
To configure default map marker chart settings for a data source configuration:
Edit the appropriate data source configuration. See Editing a Data Source Configuration.
Select the Charts tab in the data source configuration wizard.
On the Standard subtab of the Charts tab, select Map: Markers.
If you want to be able to display the data collected by this data source configuration as a map marker chart, make sure the Map: Markers checkbox is selected.
Default map marker chart settings appear on the right side of the page.
Configure the default settings as follows:
Setting Description Latitude
Select the latitude field that should be used for map marker charts with this data source.
Longitude Select the longitude field that should be used for map marker charts with this data source. Lat/Long Limit Specify the maximum number of markers to be displayed on the map. Max Zoom Specify the maximum level to which you can zoom and view the markers. Start Zoom Specify the level at which you can start to zoom and view markers for the region.

If you want map marker charts for a data source to support live mode and data playback, be sure that the data source includes a time field and that it meets the requirements for live mode and playback. See Live Mode and Historical Playback.
