Highcharts如何将列标题用作X轴而不是图例

// 列标题数组
var columnTitles = ['标题1', '标题2', '标题3'];

// 数据数组
var data = [
  { '标题1': 10, '标题2': 20, '标题3': 30 },
  { '标题1': 40, '标题2': 50, '标题3': 60 },
  { '标题1': 70, '标题2': 80, '标题3': 90 }
];

// Highcharts配置选项
var options = {
  chart: {
    type: 'column'
  },
  xAxis: {
    categories: columnTitles,
    title: {
      text: '列标题'
    }
  },
  yAxis: {
    title: {
      text: 'Y轴标题'
    }
  },
  series: []
};

// 将数据转换为Highcharts的series格式
for (var i = 0; i < columnTitles.length; i++) {
  var seriesData = [];
  for (var j = 0; j < data.length; j++) {
    seriesData.push(data[j][columnTitles[i]]);
  }
  options.series.push({
    name: columnTitles[i],
    data: seriesData
  });
}

// 创建图表
var chart = Highcharts.chart('container', options);
