如何在3d highcharts上设置背景图像？

var chart = Highcharts.chart('container', {
    chart: {
        type: 'column',
        options3d: {
            enabled: true,
            alpha: 15,
            beta: 15,
            depth: 50,
            viewDistance: 25
        }
    },
    // 其他配置项...
});

<div id="container" class="chart-container"></div>

.chart-container {
    background-image: url('path/to/image.jpg');
    background-size: cover;
    background-repeat: no-repeat;
}

chart.redraw();
