title: Clear all Y Coordinates , given a X coordinate in PointCollection C#
body: <p>I wanted to know is there any built in method to clear all the Y Points if i have dX point in Point Collection , let's say i have a point </p>
  
  <pre><code>new System.Windows.Point(dX, dY)
  </code></pre>
  
  <p>I'm trying to clear the whole dY for dX + 1.</p>
  
  <p>I'm trying to clear a Line which gets drawn from the previous loop , i can create a loop to clear it , but i wanted to know if there is any built in optimal method to accomplish that.</p>
  
  <p>Thank you  </p>
