plotBands Labels have option to be hidden when no space, specially in xAxis
plotBands Labels right now if there is no any space (for example: horizontally), specially in highstock 7.2.0
will be shown out of width of the rectangle.
so it will be better we have an option and by defualt be on that make them hidden when no space, specially in xAxis.
Thanks for your request!
You can currently set a fixed width for the label, but it doesn’t scale though: http://jsfiddle.net/highcharts/sr30L4en/.
In order to implement this, the `style.width` would have to be dynamically set to the plot band width.
