},
lineStyle:{
type:'solid',
color: '#FF1D00',
width: 1
},
data: [{xAxis: '40', name:'危险 (40dB)'},

},
二、多条不同色彩 markLine

data: [{yAxis: '40',lineStyle: {color: '#FF1D00'},label: {color: '#FF1D00',formatter:'危险 (40dB)',fontSize:10}},
{yAxis: '25',lineStyle: {color: '#FF7804'},label: {color: '#FF7804',formatter:'异样 (25dB)',fontSize:10}}]
