option = {
xAxis: {
type: 'category',
data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
},
yAxis: {
type: 'value'
},
series: [{
data: [820, 932, 901, 934, 1290, 1330, 1320],
type: 'line',
markPoint: {
data: [
{type: 'max', name: '最大值'},
{type: 'min', name: '最小值'}
]
},
markLine: {
data: [
{type: 'average', name: '平均值'}
]
}
}]

};
