很简单

按你上面的图

创建两个坐标系

然后把想同时显示和消失的那几项设置成相同的name就行

给你个代码示例

option = {

legend:{

show:true,

data:['111','222']

},

xAxis: [{

data: ['Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat']

}, {

data: ['Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat'],

gridIndex: 1

}],

yAxis: [{}, {

gridIndex: 1

}],

grid: [{

bottom: '60%'

}, {

top: '60%'

}],

series: [

{

type: 'line',

name: '111',

data: [1220, 1832, 1491, 2354, 2960, 3730, 8310]

},

{

type: 'line',

name: '222',

data: [2220, 1832, 1941, 2534, 2960, 3370, 3110]

},

{

type: 'line',

name: '111',

data: [2240, 1821, 1917, 2334, 23290, 330, 3610],

xAxisIndex: 1,

yAxisIndex: 1

},

{

type: 'line',

name: '222',

data: [220, 182, 191, 234, 290, 330, 310],

xAxisIndex: 1,

yAxisIndex: 1

},

]

};
