1、首先设置 echarts 内容:
const myChart3 = this.$echarts.init(document.getElementById('myChart3'));
myChart3.setOption({
tooltip: {
},
grid:{
},
legend: {
x: 'center',
icon: "circle",
itemWidth: 10,
itemHeight: 10,
textStyle: {
fontSize: 12
},
data: ['成功笔数', '拒付笔数', '退款笔数', '拒付率']
},
calculable: true,
triggerEvent: true,
xAxis: [
{
type: 'category',
// triggerEvent: true,
data: date
}
],
yAxis: [
{
type: 'value',
// triggerEvent: true,
splitLine: {
show: true,
lineStyle: {
type: 'dashed'
}
}
},
{
splitLine: {
show: true,
lineStyle: {
type: 'dashed'
}
},
splitNumber: 6,
type: 'value',
}
],
series: [
{
name: '成功笔数',
type: 'bar',
barWidth: 10,
itemStyle: {
normal: {
color: '#2566FA',
barBorderRadius: [10, 10, 0, 0],
}
},
data: date_4,
// data: [10,20,10,5,10,90,30],
yAxisIndex: 0
},
{
name: '拒付笔数',
type: 'bar',
barWidth: 10,
itemStyle: {
normal: {
color: '#F71F45',
barBorderRadius: [10, 10, 0, 0],
}
},
data: data_1,
// data: [10,20,10,5,10,90,30],
yAxisIndex: 0
},
{
name: '退款笔数',
type: 'bar',
barWidth: 10,
itemStyle: {
normal: {
color: '#f7bb3d',
barBorderRadius: [10, 10, 0, 0],
}
},
data: data_2,
// data: [10,20,10,5,10,90,30],
yAxisIndex: 0
},
{
name: '拒付率',
type: "line",
smooth: true,//平滑曲线
itemStyle: {
normal: {
color: '#F99025'
}
},
data: data_3,
// data: [10,20,60,50,0,5,7],
yAxisIndex: 1
},
]
});
2、鼠标移入事件:
myChart3.getZr().on('mousemove', function(params) { this.newimgAnalysisList = []; let pointInPixel = [params.offsetX, params.offsetY]; let pointInGrid = myChart3.convertFromPixel({seriesIndex: 0}, pointInPixel); let xIndex = pointInGrid[0]; let op = myChart3.getOption(); let machineName = op.xAxis[0].data[xIndex]; //获取x轴名字 for(const i in this.imgAnalysisList) { //根据x轴名字,匹配后端返回过来的数据 if(!this.imgAnalysisList.hasOwnProperty(i)) continue; if(machineName === this.imgAnalysisList[i].country) { this.newimgAnalysisList.push(this.imgAnalysisList[i]); } } });
3、若获取不到 vue 下的 data,则需要把 myChart3.getZr().on('mousemove', function(params){.....} 改成: myChart3.getZr().on('mousemove', (params) => {}) 箭头函数即可。
4、.getZr() :指的是当去掉它的时候,鼠标 点击/移入 等事件,只能在点上,加上它的时候,则可以把事件绑定为整个灰色区域

5、另:echarts 支持的常见鼠标事件类型有, “ click ”、“ dblclick ”、“ mousedown ”、“ mousemove ”、“ mouseup ”、" mouseover "、" mouseout "、" globalout "、" contextmenu " 事件,可根据需要修改。
