问题描述
要将 echarts 散点图连成线，你需要设置dataset，然后在配置项中设置连接线的系列类型为 ‘line’。
dataset: [
{
source: data.data }
]
解决方案：
上代码：
<template>
<div ref="myEchart"/>
</template>
<script>
import echarts from 'echarts'
export default {
data() {
return {
list:{
name: '轨迹',
data: [
['10','20'],['20','30'],['10','30'],['30','50'],['40','60'],['30','20'],['60','50'],['80','100'],['50','20'],['60','50'],['70','60'],['80','60'],
['100','80'],['90','50'],['50','60'],['60','70'],['70','80'],['80','60'],['60','70'],['60','100'],['60','80'],['40','60'],['50','90'],['100','80']
]
}
}
},
mounted() {
this.$nextTick(()=>{
this.initChart()
})
},
beforeDestroy() {
if(!this.chart) {
return
}
this.chart.dispose()
this.chart = null
},
methods: {
initChart() {
this.chart = echarts.init(this.$refs.myEchart);
this.setOptions(this.list)
},
setOptions(data) {
this.chart.setOption({
tooltip: {
trigger: 'axis',
},
xAxis: {
splitLine: {
show: false
},
axisLine: {
lineStyle: {
type: 'solid',
color: '#fff',
width: '1'
}
},
axisLabel: {
textStyle: {
color: "#fff",
fontSize: "12"
}
}
},
yAxis: {
axisTick: {
show: false
},
splitLine: {
show: false
},
axisLabel: {
textStyle: {
color: "#fff",
fontSize: "10"
}
},
axisLine: {
lineStyle: {
type: 'solid',
color: '#fff',
width: '1'
}
},
},
dataset: [
{
source: data.data }
],
series: [
{
name: 'scatter',
type: 'scatter'
},
{
name: data.name,
type: 'line',
smooth: true
}
]
})
}
}
}
</script>
