title: How to draw a Horizontal line using Highcharts DotNet C#
body: <p>I was wondering how it would be possible to draw a solid horizontal line using the Highcharts framework. <br>
  <strong>Purpose:</strong> The purpose for these lines is that I want to have constraints at a certain value.<br>
  <strong>Extra Information:</strong></p>
  
  <ol>
  <li>Technology: ASP.NET MVC3, Highcharts DotNet C# Framework</li>
  <li>Framework I am using: <a href="http://dotnethighcharts.codeplex.com/" rel="nofollow noreferrer">http://dotnethighcharts.codeplex.com/</a></li>
  </ol>
  
  <p><strong>Example:</strong><br>
  <img src="https://i.stack.imgur.com/WtQOn.png" alt="enter image description here"></p>
  
  <p>This is an example of what I kind of want, except the red and green lines will be control lines. I do not want to red and green lines to have points, but to be a solid line. </p>
  
  <p><strong>Current Code of how I generated the graph above</strong></p>
  
  <pre><code>        Highcharts chart = new Highcharts("chart");
          chart.SetXAxis(new XAxis
          {
              Categories = new[] { "Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec" }
          });
          chart.SetSeries(new[]{
              new Series
              {
                  Data = new Data(new object[] { 29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4 })
              },
              new Series
              {
                  Data = new Data(new object[] { 250, 250, 250, 250, 250, 250, 250, 250, 250, 250, 250, 250 })
              },
              new Series
              {
                  Data = new Data(new object[] { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 })
              }
  
          });
  </code></pre>
