title: Highcharts - event after loading series
body: <p>I have a few series in the chart. By clicking on some buttons, they are displayed. Series use "hide". Showing occurs only on clicks on the button.</p>
  
  <pre><code>{    
      id: "meq",
      name: "Margin/Equity",
      type: "candlestick",
      data: data.candle,
      color: "#ffa659",
      yAxis: 1,
      hide:true,
      visible:false
   }
  </code></pre>
  
  <p>But at the beginning of loading charts showing all the series and hiding late.
  I want to put a picture until the complete download.
  "Load" triggered before than I need. (All series are shown)</p>
  
  <pre><code>events: {
  load: function() {
  $(".loading-icon").addClass("hidden"); // class for image befor loading
  }
  }
  </code></pre>
  
  <p>And it does not help to put a picture in:</p>
  
  <pre><code>xAxis: {
  events: {
  afterSetExtremes: function(e) {
  $(".loading-icon").addClass("hidden");
  }
  }
  </code></pre>
  
  <p>How do I hide the picture only after a full load series?</p>
