title: Highcharts drilldown resize yAxis on drilldown/drillup
body: <p>How can I resize the yAxis on drilldown/drillup? </p>
  
  <p>I have a drilldown column chart that could have series data from 100k+ to 1. Some categories in the drilldown are tiny compared to the yAxis extreme and are hard to make out the data label.</p>
  
  <pre><code>$("#chart").highcharts({
    chart: {
      type: 'column'
    },
    xAxis: {
      type: 'category'
    },
    yAxis: {
      minTickInterval: 100,
      max: 1000
    },
    series: [
      {
        data: [
               {drilldown:1,"name":"Apples","y":203},
               {drilldown:2,"name":"Bananas","y":599},
               {drilldown:3,"name":"Oranges","y":427}
              ]
      }
    ],
      drilldown: {
          series: [
            {
              id: 1,
              name: "Apples",
              data: [["Foo", 58], ["Bar", 100], ["Baz", 45]]
            },
            {
              id: 2,
              name: "Apples",
              data: [["Foo", 58], ["Bar", 100], ["Baz", 45]]
            },
            {
              id: 3,
              name: "Apples",
              data: [["Foo", 58], ["Bar", 100], ["Baz", 45]]
            }
          ]
      }
  });
  </code></pre>
