A background grid defines the default color and context grid for display behind a map or scene surface. The background grid determines what an empty MapView or scene Surface looks like. An instance of this class can be used to set a default backdrop that an ArcGISMap or ArcGISScene will display on top of.
True if grid lines are visible on the BackgroundGrid.color, false otherwise. In the context of MapView, this value indicates if the BackgroundGrid.lineColor is visible. In the context of SceneView, this value indicates if both the BackgroundGrid.color and the BackgroundGrid.lineColor are visible. The default value is true.
