如何在FusionChart js multilevelpie中使切片成为链接？

问题描述

我想在饼图中创建可点击的链接。

我使用了FusionCharts.js。 如何在图表中建立链接？

例如（FusionChart.js用切片“海鲜”，“面包”，“服装”，“太阳镜”，“食品和饮料”，“服装和配饰”创建多层次图表）：

FusionCharts.ready(function() {
  var topProductsChart = new FusionCharts({
    type: 'multilevelpie',
    renderAt: 'chart-container',
    id: "myChart",
    width: '400',
    height: '400',
    dataFormat: 'json',
    dataSource: {
      "chart": {
        "theme": "fusion",
        "caption": "Split of Top Products Sold",
        "subCaption": "Last Quarter",
        "captionFontSize": "14",
        "subcaptionFontSize": "14",
        "baseFontColor": "#333333",
        "baseFont": "Helvetica Neue,Arial",
        "basefontsize": "9",
        "subcaptionFontBold": "0",
        "bgColor": "#ffffff",
        "canvasBgColor": "#ffffff",
        "showBorder": "0",
        "showShadow": "0",
        "showCanvasBorder": "0",
        "pieFillAlpha": "60",
        "pieBorderThickness": "2",
        "hoverFillColor": "#cccccc",
        "pieBorderColor": "#ffffff",
        "useHoverColor": "1",
        "showValuesInTooltip": "1",
        "showPercentInTooltip": "0",
        "numberPrefix": "$",
        "plotTooltext": "$label, $$valueK, $percentValue",
        "pieRadius": "170"
      },
      "category": [{
        "label": "Sales by category",
        "color": "#ffffff",
        "value": "150",
        "category": [{
            "label": "Food & {br}Beverages",
            "color": "#f8bd19",
            "value": "55.5",
            "category": [{
                "label": "Breads",
                "color": "#f8bd19",
                "value": "11.1"
              },
              {
                "label": "Seafood",
                "color": "#f8bd19",
                "value": "6.66"
              }
            ]
          },
          {
            "label": "Apparel &{br}Accessories",
            "color": "#e44a00",
            "value": "42",
            "category": [{
                "label": "Sun Glasses",
                "color": "#e44a00",
                "value": "10.08"
              },
              {
                "label": "Clothing",
                "color": "#e44a00",
                "value": "18.9"
              },
            ]
          },
        ]
      }]
    }
  });

  topProductsChart.render();
});

我希望这些切片，例如“面包”，成为可点击的链接。
