# navigator.adaptToUpdatedData

Whether the navigator and scrollbar should adapt to updated data in the base X axis. When loading data async, as in the demo below, this should be `false`. Otherwise new data will trigger navigator redraw, which will cause unwanted looping. In the demo below, the data in the navigator is set only once. On navigating, only the main chart content is updated.
