comment changer la couleur de l'itinéraire dans google maps v3

J'utilise ceci code pour obtenir des directions entre deux points. Est-il possible de changer la couleur de l'itinéraire du bleu? Je n'utilise pas de polyligne dans mon code.

Merci d'avance :)

Vous pouvez spécifier la couleur de la ligne lorsque vous créez le DirectionsRenderer, en utilisant la structure facultative DirectionsRendererOptions .

Cela fonctionne pour moi, en changeant simplement la ligne où l'objet DirectionsRenderer est créé:

<!DOCTYPE html>
<html>
  <head>
    <meta name="viewport" content="initial-scale=1.0, user-scalable=no">
    <meta charset="utf-8">
    <title>Directions service</title>
    <link href="https://google-developers.appspot.com/maps/documentation/javascript/examples/default.css" rel="stylesheet">
    <script src="https://maps.googleapis.com/maps/api/js?v=3"></script>
    <script>
var directionsDisplay;
var directionsService = new google.maps.DirectionsService();
var map;

function initialize() {
  directionsDisplay = new google.maps.DirectionsRenderer({
    polylineOptions: {
      strokeColor: "red"
    }
  });

  var mapOptions = {
    zoom:7,
    mapTypeId: google.maps.MapTypeId.ROADMAP,
    center: {lat: 41.850033, lng: -87.6500523}
  }
  map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
  directionsDisplay.setMap(map);
}

function calcRoute() {
  var start = document.getElementById('start').value;
  var end = document.getElementById('end').value;
  var request = {
      Origin:start,
      destination:end,
      travelMode: google.maps.DirectionsTravelMode.DRIVING
  };
  directionsService.route(request, function(response, status) {
    if (status == google.maps.DirectionsStatus.OK) {
      directionsDisplay.setDirections(response);
    }
  });
}

google.maps.event.addDomListener(window, 'load', initialize);
    </script>
  </head>
  <body>
    <div id="panel">

vous pouvez changer la couleur en changeant la couleur du trait :) aussi simple que ça

    directionsService = new google.maps.DirectionsService();
    directionsDisplay = new google.maps.DirectionsRenderer({ polylineOptions: { strokeColor: "#8b0013" } });
    directionsDisplay.setMap(map);
    directionsDisplay.setOptions({ suppressMarkers: true });


        calcRoute();
