title: Highcharts stacked column bar with line
body: <p>I want this stacked column chart
  <a href="http://jsfiddle.net/gh/get/jquery/1.9.1/highslide-software/highcharts.com/tree/master/samples/highcharts/demo/column-stacked/" rel="nofollow">Demo column stacked</a> with this <a href="http://jsfiddle.net/gh/get/jquery/1.9.1/highslide-software/highcharts.com/tree/master/samples/highcharts/demo/combo-dual-axes/" rel="nofollow">Basic Column with line</a>. What i want is have a line in this stacked column chart. </p>
  
  <p>Note: I've found this example already present in stackoverflow, <a href="http://jsfiddle.net/rahulroybentley/3fZx7/8/" rel="nofollow">Stacked bar with line</a>, but can't really make it a stacked column with line.</p>
  
  <p>I'm using HighCharts .Net plugin, my code for stacked bar is: </p>
  
  <pre><code>Highcharts chart = new Highcharts("chart");
  
      chart.SetSeries(new[]
                  {
                      new Series { Name = "Title1", Data = new Data(data1) },
                      new Series { Name = "Title2", Data = new Data(data2) },
                      new Series { Name = "Title3", Data = new Data(data3) },
                      new Series { Name = "Title4", Data = new Data(data4) }
                  });
  
      chart.InitChart(new Chart {DefaultSeriesType = ChartTypes.Column});
      chart.SetTitle(new Title{Text = "Graph title" });
      chart.SetXAxis(new XAxis { Categories = xaxis });
      chart.SetYAxis(new YAxis
              {
                  Min = 0,
                  Title = new YAxisTitle { Text = "Total hit" },
                  StackLabels = new YAxisStackLabels
                  {
                      Enabled = true,
                      Style = "fontWeight: 'bold', color: (Highcharts.theme &amp;&amp; Highcharts.theme.textColor) || 'gray'"
                  }
              });
      chart.SetLegend(new Legend
              {
                  Layout = Layouts.Horizontal,
                  Align = HorizontalAligns.Right,
                  VerticalAlign = VerticalAligns.Top,
                  X = -100,
                  Y = 20,
                  Floating = true,
                  BackgroundColor = new BackColorOrGradient(ColorTranslator.FromHtml("#FFFFFF")),
                  BorderColor = ColorTranslator.FromHtml("#CCC"),
                  BorderWidth = 1,
                  Shadow = false
              });
      chart.SetPlotOptions(new PlotOptions
              {
                  Column = new PlotOptionsColumn
                  {
                      Stacking = Stackings.Normal,
                      DataLabels = new PlotOptionsColumnDataLabels
                      {
                          Enabled = true,
                          Color = Color.White
                      }
                  }
              });
      ltrChart.Text = chart.ToHtmlString();
  </code></pre>
