1.定义一个定时器标识

let timer: NodeJS.Timer; // 定时器

2.定义展示的数据的条数

const dataZoomEndValue = 5; // 数据窗口范围的结束数值(一次性展示几个)

3.设置datazoom的相关参数

dataZoom: [{show: false, // 是否显示滑动条xAxisIndex: 0, // 表示从X轴的零刻度线开始的startValue: 0, // 数据窗口范围的起始数值endValue: dataZoomEndValue // 数据窗口范围的结束数值(一次性展示几个)}
],

4.定义开始动画定时器和结束动画定时器的两个函数

// 鼠标移入echarts图表暂停动画
const stopAnimation = () => {clearInterval(timer);
};
// 鼠标移出echarts图表开始动画
const startAnimation = (myChart: echarts.ECharts, option: any, Xdata: Array<string>, dataZoomEndValue: number) => {timer = setInterval(() => {// 每次向后滚动一个，最后一个从头开始if (option.dataZoom[0].endValue === Xdata.length - 1) {option.dataZoom[0].startValue = 0; // 数据窗口范围的起始数值option.dataZoom[0].endValue = dataZoomEndValue; // 数据窗口范围的结束数值} else {option.dataZoom[0].startValue = option.dataZoom[0].startValue + 1; // 数据窗口范围的起始数值option.dataZoom[0].endValue = option.dataZoom[0].endValue + 1; // 数据窗口范围的结束数值}myChart.setOption(option);}, 2000);
};

5.开启定时器动画，以及鼠标移入移除ecahrts暂停和开始动画效果

if (Xdata.length > 0) {startAnimation(myChart, option, Xdata, dataZoomEndValue);
}
// 给echarts图表绑定鼠标移入移除事件
myChart.on("mouseover", function () {stopAnimation();
});
myChart.on("mouseout", function () {startAnimation(myChart, option, Xdata, dataZoomEndValue);
});

6.最后别忘了清除定时器

onUnmounted(() => {stopAnimation();
});
