Hi,
I need to locally save the navigator setup.
What I need is saving the current "Zoom" and the posizion of the window in order to be able to load it in a second moment.
Where would you like to save that setup? To save the current zoom and position of the window you need to get current extremes and apply them when you need to.
Yes, that is all you need. Also I think that you might want to try afterSetExtremes event. It should help you catch current extremes, you could even use that event to save them in local storage. API reference:https://api.highcharts.com/highcharts/x ... etExtremes
