点击echart图表的x轴线或者x轴坐标,获取x轴的数据,高亮显示x轴坐标。
//设置x轴坐标可以点击
xAxis: [{
triggerEvent: true,
axisLabel: {
color: function (value, index) {
return value == time ? '#21aced' : '#fff';
},
clickable: true,
},
}],
let time = ""
//点击x轴线
myChart.getZr().on('click', params => {
const pointInPixel = [params.offsetX, params.offsetY]
if (myChart.containPixel('grid', pointInPixel)) {
const xIndex = myChart.convertFromPixel({ seriesIndex: 0 }, [params.offsetX, params.offsetY])[0]
time = option.xAxis[0].data[xIndex]
myChart.resize();
console.log(time)
}
})
//点击x轴坐标
myChart.on('click', 'xAxis.category', function (params, node) {
time = params.value
myChart.resize();
console.log(time)
});
