        title: {
            text: '饼图程序调用高亮示例',
            left: 'center'
        },
        tooltip: {
            trigger: 'item',
            formatter: '{a} <br/>{b} : {c} ({d}%)'
        },
        legend: {
            orient: 'vertical',
            left: 'left',
            data: ['直接访问', '邮件营销', '联盟广告', '视频广告', '搜索引擎']
        },
        series: [
            {
                name: '访问来源',
                type: 'pie',
                radius: '55%',
                center: ['50%', '60%'],
                data: [
                    { value: 335, name: '直接访问' },
                    { value: 310, name: '邮件营销' },
                    { value: 234, name: '联盟广告' },
                    { value: 135, name: '视频广告' },
                    { value: 1548, name: '搜索引擎' }
                ],
                emphasis: {
                    itemStyle: {
                        shadowBlur: 10,
                        shadowOffsetX: 0,
                        shadowColor: 'rgba(0, 0, 0, 0.5)'
                    }
                }
            }
        ]
    }
}

let currentIndex = -1;

setInterval(function() {
  var dataLen = option.series[0].data.length;
  // 取消之前高亮的图形
  myChart.dispatchAction({
    type: 'downplay',
    seriesIndex: 0,
    dataIndex: currentIndex
  });
  currentIndex = (currentIndex + 1) % dataLen;
  // 高亮当前图形
  myChart.dispatchAction({
    type: 'highlight',
    seriesIndex: 0,
    dataIndex: currentIndex
  });
  // 显示 tooltip
  myChart.dispatchAction({
    type: 'showTip',
    seriesIndex: 0,
    dataIndex: currentIndex
  });
}, 1000);

Current Behavior

5.5.0版本无法进行手动高亮饼图，其他图没有问题

instance.dispatchAction({
                    type: 'highlight',
                    seriesIndex: 0,
                    dataIndex: 1
                })

当seriesIndex 设置为0时会报错 信息如下：

Expected Behavior

期待正常高亮饼图

Found the problem

// good
let currentIndex = -1;

setInterval(function() {
  var dataLen = option.series[0].data.length;
  // 取消之前高亮的图形
  myChart.dispatchAction({
    type: 'downplay',
    seriesIndex: 0,
    dataIndex: currentIndex
  });
  currentIndex = (currentIndex + 1) % dataLen;
  // 高亮当前图形
  myChart.dispatchAction({
    type: 'highlight',
    seriesIndex: 0,
    dataIndex: currentIndex
  });
  // 显示 tooltip
  myChart.dispatchAction({
    type: 'showTip',
    seriesIndex: 0,
    dataIndex: currentIndex
  });
}, 1000);

// bad
  var dataLen = option.series[0].data.length;
  // 取消之前高亮的图形
  myChart.dispatchAction({
    type: 'downplay',
    seriesIndex: 0,
    dataIndex: 1
  });
  // 高亮当前图形
  myChart.dispatchAction({
    type: 'highlight',
    seriesIndex: 0,
    dataIndex: 1
  });
  // 显示 tooltip
  myChart.dispatchAction({
    type: 'showTip',
    seriesIndex: 0,
    dataIndex: 1
  });

Why do errors occur when setting the first or other dataindexes separately？ Can someone help me solve this problem?

你是 setOption 之后，立即调用 dispatchAction 吗？需要等一下，比如加上一个 setTimeout(() => { // ... }, 0)。

不是的，我是在echarts渲染完成后调用高亮函数的

贴下代码片段，看看怎么写的。
