Works fine with Highstock v6.0.7: http://jsfiddle.net/BlackLabel/6cqfz44n/
Using 'setExtremes' or setting 'min' do not affect the x axis.

It looks like this problem is caused by: f1f4adc
Having the same issue. Did you find a fix or workaround @ppotaczek?
Demo with fix applied: http://jsfiddle.net/BlackLabel/quxLews1/24/
Note: In the next versions, you need to set xAxis.min
for both, main and the navigator xAxis: http://jsfiddle.net/BlackLabel/quxLews1/23/ to reflect extremes in the navigator.
