AmCharts-图表div之外的切片标签

Question

当我创建包含大量数据的漏斗图时，标签就在图表div之外，就像这样

是否可以解决此问题，或者是否需要创建仅具有图例的另一个div？

        var userInfo = JSON.parse('@Html.Raw(DataJson)');
        var chart = AmCharts.makeChart("chartdiv", {
            "type": "funnel",
            "theme": "light",
            "dataProvider": userInfo,
            "balloon": {
                "fixedPosition": false
            },
            "valueField": "Quantidade",
            "titleField": "Variac",
            "marginRight": 250,
            "marginLeft": 30,
            "startX": 0,
            "depth3D": 50,
            "angle": 25,
            "outlineAlpha": 1,
            "outlineColor": "#FFFFFF",
            "outlineThickness": 0.5,
            "labelPosition": "right",
            "balloonText": "[[Variac]]: [[Quantidade]]",
        });

这里是演示该问题的演示。

无法防止标签离开图表div，但是您可以通过设置hideLabelsPercent值来隐藏较小的切片，然后创建一个列出所有切片的图例来解决此问题。 / p>

AmCharts.makeChart("chartdiv", {
  // ...
  hideLabelsPercent: 2, //hide labels of slices that take up < 2% in size
  // ...
});

由于您有大量数据，因此可以使用divId在外部div中创建图例，以便为图表和图例分别留出空间。

var chart = AmCharts.makeChart("chartdiv", {
  "type": "funnel",
  "theme": "light",
  "dataProvider": [{
      "title": "Website visits",
      "value": 200
    }, {
      "title": "Downloads",
      "value": 123
    }, {
      "title": "Requested price list",
      "value": 98
    }, {
      "title": "Contaced for more info",
      "value": 72
    }, {
      "title": "Purchased",
      "value": 35
    }, {
      "title": "Contacted for support",
      "value": 35
    }, {
      "title": "Purchased additional products",
      "value": 26
    },
    {
      "title": "Downloads",
      "value": 123
    }, {
      "title": "Requested price list",
      "value": 98
    }, {
