title: How to change the path of a Polyline in Maps API v3?
body: <p>There is a way to change the position of a polyline with the Google Maps API v3 in Javascript ?</p>
  
  <p>A way to change the "path" option for a line already drawn ? I already changed the position of the "Circle" but not  "RadiusLine"...</p>
  
  <p><strong>Map init code</strong> :</p>
  
  <pre><code>var latlng = new google.maps.LatLng(lat, lng);
          var map = new google.maps.Map(document.getElementById('map'),{
              zoom: 13,
              center: latlng,
              mapTypeId: google.maps.MapTypeId.HYBRID,
              streetViewControl: false
          });
  
          var marker = new google.maps.Marker({
              position: latlng,
              map: map
          });
  
          var sunCircle = {
            strokeColor: "#c3fc49",
            strokeOpacity: 0.8,
            strokeWeight: 2,
            fillColor: "orange",
            fillOpacity: 0.15,
            map: map,
            center: latlng,
            radius: 1500
          };
  
          var origin = sunCircle.center;
          var endpoint = google.maps.geometry.spherical.computeOffset(sunCircle.center,sunCircle.radius,180+sunPos);
  
          var radiusLineSettings = {
              clickable: false,
              map: map,
              strokeColor: "orange",
              strokeWeight: 10,
              path: [origin,endpoint]
          };
          Circle = new google.maps.Circle(sunCircle);
          RadiusLine = new google.maps.Polyline(radiusLineSettings);
