How to disable click with Angularjs2 + Amcharts Map

I have now drawn a map using typescript + Angularjs2 + amcharts
how can I invalidate click events in each area of the map
are there any attributes that can be controlled?

this.chart= this.AmCharts.makeChart ("chartdiv", {

)

  "type": "map",
  "theme": "light",
  "colorSteps": 16,
  "dataProvider": {
    "map": "usaLow",
    "areas": []
  },
  "areasSettings": {
    "balloonText": "",
    "selectable": false,
    "outlineColor": "-sharp333333"
  },
  "valueLegend": {
    "right": 10,
    "minValue": "little",
    "maxValue": "a lot"
  },
  "export": {
    "enabled": true
  }
});
