title: Highcharts: Plot multiple values in single category
body: <p>I'm quite new to Highcharts. I want to make one sample chart like:</p>
  
  <p><img src="https://i.stack.imgur.com/HUxnL.png" alt="Highchart Column And Spline"></p>
  
  <p>Main problem is that, multiple values in single category. I couldn't mitigate this.</p>
  
  <p>I've written something like this</p>
  
  <pre><code>$('#container').highcharts({
      title: '',
      credits: {
        enabled: false
      },
      xAxis: {
        categories: ['Jan', 'Feb', 'Mar']
      },
      yAxis: {
        min: 0,
        title: {
          text: ''
        }
      },
      series: [
        {
          type: 'column',
          showInLegend: false,
          data: [[0, 5000, 11000], [0, 6000, 10000], [0, 8000, 5000], [1000, 2000, 4000], 
            [1000, 9000, 4800], [1500, 10000, 4000], [0, 6500, 4500]],
          color: '#75b5ec'
        },
        {
          type: 'spline',
          data: [3, 2.67, 3],
          showInLegend: false,
          marker: {
            lineWidth: 2,
            lineColor: '#000000',
            fillColor: 'white'
          }
        }
      ]
    });
  </code></pre>
  
  <p>Please help. Thanks in advance.</p>
