How to use visualMap to control two or more series at the same time

[lisccc]

Please help me. How to use visualMap to control the display of two series named Target at the same time without affecting other series, use one controller to control these two targets? Specifying two seriesIndex in visualMap will create two controllers, which I don't want to see.

series: [{
    name: 'AP',
    type: 'scatter3D',
    data: mydataset,
    symbol: 'triangle',
    symbolSize: 30,
    color: '#000',
    itemStyle: {
        borderColor: '#fff',
        borderWidth: 2,
    },
}, {
    name: 'hidden',
    type: 'bar3D',
    stack: 'stack',
    data: floor1.map(function(item, idx) {
        return [floor1[0], floor1[1], 1]
    }),
    barSize: [10, 10],
    itemStyle: {
        opacity: 0,
    },
}, {
    name: 'Target',
    data: floor1,
    type: 'bar3D',
    stack: 'stack',
    barSize: [10, 10],
    itemStyle: {
        opacity: 0.6,
    }
}, {
    name: 'hidden',
    type: 'bar3D',
    stack: 'stack',
    data: floor2.map(function(item, idx) {
        return [floor2[0], floor2[1], 5 - bar_height, floor2[3]]
    }),
    barSize: [10, 10],
    itemStyle: {
        opacity: 0,
    },
}, {
    name: 'Target',
    type: 'bar3D',
    stack: 'stack',
    data: floor2,
    barSize: [10, 10],
    itemStyle: {
        opacity: 0.6,
    },
}]
