Event to bar category

[theking2]

Is there a way to attach an event to the category area (mouse over lightblue) and get the name of the category for further processing?

Yes, you can use the mouseover event on plotBands and refer to some information from the chart via this:

xAxis: {
  plotBands: [{
    from: 1.5,
    to: 3.5,
    events: {
      mouseover: function () {
        console.log('mouseover on plotband', this);
      }
    }
  }]
}
