Amcharts graph - Hyperlink for chart columns to custom URLs to open in a new tab/window

问题

I am trying to make a amcharts graph with columns linked to custom urls and want the urls to open in a new tab/window. I tried adding this code to the graph object but it does not work, it is opening link in same tab/window -

"listeners": [{
      "event": "clickItem",
      "method": function(event) {
window.open(event.serialDataItem.dataContext.url, '_blank');
      }
    }],

Please tell what I am doing wrong. I do not want to use Jquery and I am new to javascript.

This is my snippet -

var chart = AmCharts.makeChart("chartdiv", {
  "type": "serial",
  "theme": "light",
  "dataProvider": [{
    "country": "USA",
    "visits": 2025,
    "url": "https://en.wikipedia.org/wiki/United_States"
  }, {
    "country": "China",
    "visits": 1882,
    "url": "https://en.wikipedia.org/wiki/China"
  }, {
    "country": "Japan",
    "visits": 1809,
    "url": "https://en.wikipedia.org/wiki/Japan"
  }, {
    "country": "Germany",
    "visits": 1322,
    "url": "https://en.wikipedia.org/wiki/Germany"
  }, {
    "country": "France",
    "visits": 1114,
    "url": "https://en.wikipedia.org/wiki/France"
  }, {
    "country": "India",
    "visits": 984,
    "url": "https://en.wikipedia.org/wiki/India"
  }, {
    "country": "Spain",
    "visits": 711,
    "url": "https://en.wikipedia.org/wiki/Spain"
  }],
  "valueAxes": [{
    "gridColor": "#FFFFFF",
    "gridAlpha": 0.2,
    "dashLength": 0
  }],
  "gridAboveGraphs": true,
  "startDuration": 1,
  "graphs": [{
    "balloonText": "[[category]]: <b>[[value]]</b>",
    "fillAlphas": 0.8,
    "lineAlpha": 0.2,
    "type": "column",
    "valueField": "visits",
    "listeners": [{
      "event": "clickItem",
      "method": function(event) {
window.open(event.serialDataItem.dataContext.url, '_blank');
      }
    }],
    "urlField": "url"
  }],
  "chartCursor": {
    "categoryBalloonEnabled": false,
    "cursorAlpha": 0,
    "zoomable": false
  },
  "categoryField": "country",
  "categoryAxis": {
    "gridPosition": "start",
    "gridAlpha": 0,
    "tickPosition": "start",
    "tickLength": 20
  }
});

html, body {
  width: 100%;
  height: 100%;
  margin: 0px;
}

#chartdiv {
	width: 100%;
	height: 100%;
}

<script src="//www.amcharts.com/lib/3/amcharts.js"></script>
<script src="//www.amcharts.com/lib/3/serial.js"></script>
<script src="//www.amcharts.com/lib/3/themes/light.js"></script>

<div id="chartdiv"></div>

回答1:

You can use urlTarget such as:

var chart = AmCharts.makeChart("chartdiv", {
  "graphs": [{
    "balloonText": "[[category]]: <b>[[value]]</b>",
    "fillAlphas": 0.8,
    "lineAlpha": 0.2,
    "type": "column",
    "valueField": "visits",
    "urlField": "url",
    "urlTarget": "_blank"
  }],
  ...
};

Change

"listeners": [{
      "event": "clickItem",
      "method": function(event) {
window.open(event.serialDataItem.dataContext.url, '_blank');
      }
    }],

listeners:[{
  event:'clickItem',
  method:function(event){
    open(event.item.url, '_blank');
  }
}]
