I list below how the body tag look like.
When I want to draw a polyline I call function CreatePolyLine as you can see 
below.
I have earlier loaded the prognosisArray with the points(x,y) that I will 
use.

My problem is what is the best way to draw a new polyline with the original 
one removed ?

var svgNS = "http://www.w3.org/2000/svg";

function CreatePolyLine()
    {
        var myPolyLine = document.createElementNS(svgNS, "polyline");

        var points = "";
        for (i = 0; i < prognosisArray.length; i++)
        {
            if (prognosisArray[i].x != 0 && prognosisArray[i].y != 0)
            {
                points += prognosisArray[i].x + "," + prognosisArray[i].y + 
" ";
            }
        }

        myPolyLine.setAttribute("points", points);
        myPolyLine.setAttribute("stroke", "blue");
        myPolyLine.setAttribute("stroke-width", "1");
        myPolyLine.setAttribute("fill", "none");
        document.getElementById("mySVG").appendChild(myPolyLine);
    }

<body>
   <div id="logo">
       <span class="headerDateTimeRight" id="mydateTime"></span>
       <img alt="" src="../Images/gotris.jpg" id="logoSize"  />
      <p>For better and smother shipping on götaälv</p>
   </div>

   <br />
   <ul id="nav">
        <li><a class="menuItem"  href="Lots.html">Pilot</a></li>
        <li><a class="menuItem" href="Viva.html">Weather</a></li>

        <li class="right"><a class="logout" onclick="return LogOut()" 
href="Login.html">Log out</a></li>
   </ul>
   <br /><br />

    <div id="meetings">
       <svg id="mySVG" xmlns="http://www.w3.org/2000/svg"
