Polyline creation from lat & long

JimMichael

I've read several examples but it looks like I'm still missing something here. Beginning with 2 pair of coordinates, e.g. -85.1, 33.4 and -85.2, 33.3, I draw circles around the points and then try to draw a polyline between them. I can buffer the points fine but having a problem with the line draw. The SpatialReference on the map and buffered points is wkid:4326.


   function drawLine(x1,y1,x2,y2) {
      var params = new esri.tasks.BufferParameters();
      var p1 = new esri.geometry.Point(x1, y1, new esri.SpatialReference({wkid:102100}) );
      var p2 = new esri.geometry.Point(x2, y2, new esri.SpatialReference({wkid:102100}) );
      var geometry = new esri.geometry.Polyline(new esri.SpatialReference( {wkid:102100} ));
      geometry = geometry.addPath([p1,p2]);
      params.geometries = [ geometry ];
      params.bufferSpatialReference = new esri.SpatialReference({wkid:102100});
      params.outSpatialReference = new esri.SpatialReference({wkid:102100});
      gsvc.buffer(params, showLineBuffer);
    }
    function showLineBuffer(geometries) {
        var symbol = new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_SOLID, new dojo.Color([255, 0, 0]), 3);
      dojo.forEach(geometries, function(geometry) {
          var graphic = new esri.Graphic(geometry,symbol);
          map.graphics.add(graphic);
      });
    }

Just trying to draw the line at this time. With a minor typo change:

geographicGeometry = geographicGeometry.addPath([p1,p2]);

this function works just fine. The geographicToWebMercator method was what I was looking for. Thank you.
