DataHub

Datahub is a container of the main dataset, providing some core functions:

  • produces view (current visible subset of the data)
  • listens to some inner update events (e.g. overlay display flag)
  • provides helper functions to make data access easier
js
let chart = new NightVision()
console.log(chart.hub)  

For example, you can use DataHub API to hide all overlays, except the main one:

js
chart.hub.allOverlays().forEach((x, i) => {
    if (x.main) return; // Except the main
    x.settings.display = false;
});
// Here we have to call one more update
// (for the legend)
chart.update();
chart.update("legend");
