您可以在'line'系列上设置pointPlacement属性值正确：

series: [{
    type: 'column',
    name: 'XYZ',
    data: [346, 336, 436, 504, 740, 902, 735, 815, 866, 763, 742, 496],
    events: {
        legendItemClick: function(event) {
            if (this.visible) {
                this.chart.get('XYZ').hide();
                this.chart.get('ABC').update({
                    pointPlacement: 0
                }, false);
            } else {
                this.chart.get('ABC').update({
                    pointPlacement: 0.15
                }, false);
                this.chart.get('XYZ').show();
            }
        }
    }

}, {
    showInLegend: false,
    pointPlacement: -0.15,
    type: 'line',
    name: 'XYZ',
    id: 'XYZ',
    data: [346, 336, 436, 504, 740, 902, 735, 815, 866, 763, 742, 496]

}, {
    type: 'column',
    name: ' ABC',
    data: [250, 311, 457, 571, 701, 716, 760, 815, 876],
    events: {
        legendItemClick: function(event) {
            if (this.visible) {
                this.chart.get('ABC').hide();
                this.chart.get('XYZ').update({
                    pointPlacement: 0
                }, false);
            } else {
                this.chart.get('XYZ').update({
                    pointPlacement: -0.15
                }, false);
                this.chart.get('ABC').show();
            }
        }
    }
}, {
    showInLegend: false,
    pointPlacement: 0.15,
    type: 'line',
    name: 'ABC',
    id: 'ABC',
    data: [250, 311, 457, 571, 701, 716, 760, 815, 876]
}],
