title: Change chart type and redraw with multiple series in Highcharts
body: <p>I have a dashboard with various charts, each with an adjacent dropdown to change the type of chart.  I'm hoping to accomplish this by redrawing the chart rather than destroying it and creating a new one.</p>
  
  <p>I first stumbled upon a solution that seems to be from the Highcharts team, but in investigating, it seems to be actually be broken.  Upon selecting "column" from the select, the chart re-renders without the first series data.  I found this to be a consistent issue...highcharts only wants to render the last series the way they are using the "addSeries" method:</p>
  
  <pre><code>for(var i=0;i&lt;series.length;i++)
  {
      serie = series[0];
      serie.chart.addSeries({
          type: newType,
          name: serie.name,
          color: serie.color,
          data: serie.options.data
      }, false);
  
      serie.remove();
  }
  
  var chart = new Highcharts.Chart(options, function(chart){
  
      $('#chartType').change(function(){
          changeType(chart.series, this.value);
      });
  
  });
  </code></pre>
  
  <p>Try selecting "column" in the select here: <a href="http://jsfiddle.net/2hLr5/" rel="nofollow">http://jsfiddle.net/2hLr5/</a></p>
  
  <p>I also found someone that had accomplished this using an older version of highcharts and jQuery 1.7.1.  You can see his working example here: <a href="http://highcharts.com/jsbin/etulob/edit#javascript,live" rel="nofollow">http://highcharts.com/jsbin/etulob/edit#javascript,live</a></p>
  
  <p>In replicating his code for my uses, I found that jQuery 1.9.1 would replicate the chart from its original column into a line chart, but it chokes when trying to switch back from a line chart to columns.  You can see this here: <a href="http://highcharts.com/jsbin/etulob/9/edit#javascript,live" rel="nofollow">http://highcharts.com/jsbin/etulob/9/edit#javascript,live</a></p>
  
  <p>My best guess is that the data for column charts has changed since previous versions of Highcharts, but thats a total stab in the dark. </p>
  
  <p>Any help would be very much appreciated.</p>
