I have a use case where I want to show entire periods, for example, the xAxis should show the entire current month. However, there might not be data for the entire month. As in, the data might start somewhere in the middle of the chart.
I really love the new mouse wheel zoom feature, so tried adding that. Works great when there's data in the entire chart, but whenever there's only data in the end portion of the chart, it doesn't.
I reproduced it here: https://jsfiddle.net/r7js8yxb/22/
Try to scroll into the data. You'll notice that it takes a few "rotations of the mouse wheel" so to speak before it starts zooming in. And when it does, the xAxis jumps to xAxis.min = xAxis.dataMin. So something's up here, I think its a bug in Highcharts. Or at least a gap in functionality, would be great if you could zoom even in these cases.
