Save zoom state

[Leggy7]

I was wondering how could be possible to save current zoom position when performing an update of the chart with new data.

At the moment to update the chart I set brand new option (e.g. chart.setOption(default_page_load_options)) with all the default values i had at page load. Thus, if i changed the zoom level or the scrolling bar position, when update occurs all get reset.

I tried to save the _zr value before option set and assign it after but it ends up in infinite recursion.

please enlight me
