更改amCharts饼图切片的颜色

// 创建饼图实例
var chart = am4core.create("chartdiv", am4charts.PieChart);

// 设置数据源
chart.data = [{
  "category": "Category 1",
  "value": 100,
  "color": "#FF0000" // 切片颜色为红色
}, {
  "category": "Category 2",
  "value": 200,
  "color": "#00FF00" // 切片颜色为绿色
}, {
  "category": "Category 3",
  "value": 300,
  "color": "#0000FF" // 切片颜色为蓝色
}];

// 配置饼图
chart.innerRadius = am4core.percent(50);
chart.radius = am4core.percent(80);
chart.startAngle = 180;
chart.endAngle = 360;

// 设置切片颜色
chart.colors.list = chart.data.map(function(item) {
  return am4core.color(item.color);
});

// 创建饼图切片
var series = chart.series.push(new am4charts.PieSeries());
series.dataFields.value = "value";
series.dataFields.category = "category";

// 显示图例
chart.legend = new am4charts.Legend();
