title: Highlighting a single point in oxyplot?
body: <p>I have an oxyplot winforms control that I'm using in a WPF project. The control takes in two lists (one for x values and one for y values), and plots a lineseries. I'm trying to get my WPF project to loop through these points one at a time and highlight (simple color change) each point the loop hits. However, I can't find a way to change just one point, only the entire series.</p>
  
  <p>For instance:</p>
  
  <pre><code>var s1 = new LineSeries();
  
  s1.Color = OxyColors.LightBlue;
  s1.MarkerFill = OxyColors.Blue;
  s1.MarkerType = OxyPlot.MarkerType.Circle;
  </code></pre>
  
  <p>This changes all the points in the lineseries to a light blue color, the line itself to blue, and the points to a circle shape.</p>
  
  <p>There's no methods or properties to change a single point though.</p>
