I added 2 series in chart with "addSeries". Set property navigator.adaptToUpdatedData to false. Then I update data for series with "setData", if user zooms chart, but navigator is updated. If I update only 1 serie all works right. How fix it?
Example:

After dig deeper into I found that the problem is with this part of the code:
data.forEach(function(item){
data2.push([item[0],item[1]+50,item[2]+50,item[3]+50,item[4]+50])
})
chart.series[0].setData(data);
chart.series[1].setData(data2);
chart.hideLoading();
Because chart.series[1] is defined as a navigator series which means that this setData config updates the navigator series.
Changing to chart.series[2] fix the issue.
