我使用Fusioncharts创建了以下小提琴。我不明白为什么图表的填充颜色是透明的。

该示例的HTML代码段：

FusionCharts.ready(function() {
  var demographicsChart = new FusionCharts({
    type: 'pie2d',
    renderAt: 'chart-container',
    width: '450',
    height: '300',
    dataFormat: 'json',
    dataSource: {
      "chart": {
        "caption": "Age profile of website visitors",
        "subCaption": "Last Year",
        "startingAngle": "120",
        "showLabels": "0",
        "showLegend": "1",
        "enableMultiSlicing": "0",
        "slicingDistance": "15",
        "showPercentValues": "1",
        "showPercentInTooltip": "0",
        "plotTooltext": "Age group : $label<br>Total visit : $datavalue",
        "theme": "fint"
      },
      "data": [{
        "label": "Teenage",
        "value": "1250400"
      }, {
        "label": "Adult",
        "value": "1463300"
      }, {
        "label": "Mid-age",
        "value": "1050700"
      }, {
        "label": "Senior",
        "value": "491000"
      }]
    }
  });
  demographicsChart.render();
});

<!-- A pie3D Chart showing percentage visiting for different age groups last year in Harry's Supermart website. Attribute : # showPercentValues set to 1 to show the values w.r.t percentage of total visits. -->

<head>
  <base href="/">
</head>
<div id="chart-container">FusionCharts will render here</div>

使用以下图表级别属性：

"caption": "Age profile of website visitors",
"subCaption": "Last Year",
"startingAngle": "120",
"showLabels": "0",
"showLegend": "1",
"enableMultiSlicing": "0",
"slicingDistance": "15",
"showPercentValues": "1",
"showPercentInTooltip": "0",
"plotTooltext": "Age group : $label<br>Total visit : $datavalue",
"theme": "fint"

问题是由于base在HTML头中使用了标签。

正如解释在这里：

问题主要不是与FusionCharts有关，而是一个通用的SVG问题。在SVG中，将渐变色应用于元素时，它实际上是“引用”页面上的另一个渐变元素。这有点类似于链接如何使用页面上的＃标签。

现在，当您在页面上设置a时，引用变得混乱了。现在，渐变引用的是基本标记中提供的具有URL的元素。

尽管如此，FusionCharts为此提供了一个解决方案。使用'FusionCharts.options.SVGDefinitionURL ='absolute';' 在您的JavaScript代码中解决此问题。您可以参考此小提琴或查看以下代码片段：

FusionCharts.ready(function() {
  FusionCharts.options.SVGDefinitionURL = 'absolute';
  var demographicsChart = new FusionCharts({
    type: 'pie2d',
    renderAt: 'chart-container',
    width: '450',
    height: '300',
    dataFormat: 'json',
    dataSource: {
      "chart": {
        "caption": "Age profile of website visitors",
        "subCaption": "Last Year",
        "startingAngle": "120",
        "showLabels": "0",
        "showLegend": "1",
        "enableMultiSlicing": "0",
        "slicingDistance": "15",
        "showPercentValues": "1",
        "showPercentInTooltip": "0",
        "plotTooltext": "Age group : $label<br>Total visit : $datavalue",
        "theme": "fint"
      },
      "data": [{
        "label": "Teenage",
        "value": "1250400"
      }, {
        "label": "Adult",
        "value": "1463300"
      }, {
        "label": "Mid-age",
        "value": "1050700"
      }, {
        "label": "Senior",
        "value": "491000"
      }]
    }
  });
  demographicsChart.render();
});

<div id="chart-container">FusionCharts will render here</div>

希望这可以帮助。
