[JIM] Overlays - Data Mappings v.6.5
- Christian Schabasser
Owned by Christian Schabasser
Data mappings enable the integration of external data sources into Custom Overlays. By reading external files, such as JSON files, at regular intervals, the Custom Overlay can be automatically updated. Below is an example that illustrates how to integrate an external data point.
