echarts画多条一元回归线

理论上两点一线，只要两个点即可

option = {
title: {
text: '',
left: 'center'
},
tooltip: {
// trigger: 'item',
// formatter: '{a} <br/>{b} : {c}'
},
lineStyle: {
normal: {
type: 'solid',
width: 30
}
},
legend: {
left: 'left',
data: ['']
},
xAxis: {
type: 'category',
name: '',
boundaryGap : false,//设置中间显示还是顶头显示
axisLine: {onZero: true},
data: ['0','1', '2', '3', '4', '5']
},
grid: {
left: '3%',
right: '4%',
bottom: '3%',
containLabel: true
},
yAxis: {
splitLine:{show: false},//去除网格线
splitArea:{show : false},//不保留网格区域
type: '',
name: ''
},
