title: Adding a string value in datapoint of line series of Oxyplot
body: <p>Can anyone please tell how to add a string value in data point of line series in Oxyplot?</p>
  
  <p>I have a list which is a key-value pair of string, double and wanted to add it to a data point.</p>
  
  <p>Example:
  string values are 10-15,15-20, ...</p>
  
  <p>double values are 10, 20, 30, ...</p>
  
  <p>I want my x-axis tick points to be displayed as for example (10-15, 15-20 and so on)</p>
  
  <p>Following is the code:</p>
  
  <pre><code>foreach (var points in list)
  {
     lineseriesobject.Points.Add(new OxyPlot.DataPoint(Convert.ToDouble(points.Key), Convert.ToDouble(points.Value)));
  }
  </code></pre>
