内容
很简单借助于
dispatchAction
来触发事件;
import * as echarts from 'echarts'; var chartDom = document.getElementById('main'); var myChart = echarts.init(chartDom); var option; option = { tooltip: { trigger: 'axis', axisPointer: { type: 'shadow' } }, legend: {}, grid: { left: '3%', right: '4%', bottom: '3%', containLabel: true }, xAxis: [ { type: 'category', data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun'] } ], yAxis: [ { type: 'value' } ], series: [ { name: 'Direct', type: 'bar', emphasis: { focus: 'series' }, data: [320, 332, 301, 334, 390, 330, 320] }, { name: 'Email', type: 'bar', stack: 'Ad', emphasis: { focus: 'series' }, data: [120, 132, 101, 134, 90, 230, 210] }, { name: 'Union Ads', type: 'bar', stack: 'Ad', emphasis: { focus: 'series' }, data: [220, 182, 191, 234, 290, 330, 310] }, { name: 'Video Ads', type: 'bar', stack: 'Ad', emphasis: { focus: 'series' }, data: [150, 232, 201, 154, 190, 330, 410] }, { name: 'Search Engine', type: 'bar', data: [862, 1018, 964, 1026, 1679, 1600, 1570], emphasis: { focus: 'series' }, markLine: { lineStyle: { type: 'dashed' }, data: [[{ type: 'min' }, { type: 'max' }]] } }, { name: 'Baidu', type: 'bar', barWidth: 5, stack: 'Search Engine', emphasis: { focus: 'series' }, data: [620, 732, 701, 734, 1090, 1130, 1120] }, { name: 'Google', type: 'bar', stack: 'Search Engine', emphasis: { focus: 'series' }, data: [120, 132, 101, 134, 290, 230, 220] }, { name: 'Bing', type: 'bar', stack: 'Search Engine', emphasis: { focus: 'series' }, data: [60, 72, 71, 74, 190, 130, 110] }, { name: 'Others', type: 'bar', stack: 'Search Engine', emphasis: { focus: 'series' }, data: [62, 82, 91, 84, 109, 110, 120] } ] }; option && myChart.setOption(option); setTimeout(function () { myChart.dispatchAction({ type: 'highlight', seriesIndex: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9], dataIndex: 1 }); myChart.dispatchAction({ type: 'showTip', seriesIndex: 0, dataIndex: 1 }); }, 1000);
实现效果
学无止境,谦卑而行.
