An array of colored bands stretching across the plot area marking an interval on the axis.
In styled mode, the plot bands are styled by the .highcharts-plot-band
class in addition to the className option.
When doing Chart.update() or Axis.update(), the plot bands are updated
by index or id. The following merging rules apply:
plotBands are not defined in the new options, all existing plot bands
are kept.plotBands are defined without ids, the existing plot bands are updated
by index. If the new array has fewer plot bands, the remaining existing
plot bands are removed. If the new array has more plot bands, the extra
ones are added. An empty array removes all existing plot bands.plotBands are defined with ids, the existing plot bands are matched
by id, and remaining unmatched existing plot bands are removed.
