I am building a website that will pull multiple lat/long points from a database and plot them on a map. The problem I'm having is when I go to set the extent to show only the points plotted, the extent only shows the first point.I'm using "map.setExtent(NewExtent, true)", and when I step through the code the line is hit for every point, but only the first call seems to matter.I've included a code snippet below. Also, this is my first ESRI project so if you see me doing something dumb, let me know and I'll correct it.Thanks for the help.Code below:
function init() {
map = new esri.Map("CallMap");
var basemap = new esri.layers.ArcGISTiledMapServiceLayer("http://server.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer", {opacity:0});
map.addLayer(basemap);
map.setExtent(esri.geometry.geographicToWebMercator(new esri.geometry.Extent((-75.646399), (40.824849), (-74.883529), (41.248469), new esri.SpatialReference({ wkid: 2271 }))));
dojo.connect(map, 'onLoad', function () {
var symbol = new esri.symbol.SimpleFillSymbol(esri.symbol.SimpleFillSymbol.STYLE_SOLID, new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_SOLID, new dojo.Color([0,0,255,0.65]), 2), new dojo.Color([0,0,255,0.35]));
addToMap(map, 41.092236000, -75.323746000, 'images/pnt.png', '149');
addToMap(map, 40.970196000, -75.277355000, 'images/pnt2.png', '19');
});
}
function addToMap(map, lat, lon, pic, dis) {
var myExtent = new esri.geometry.Extent((lon - 0.003), (lat - 0.003), (lon + 0.003), (lat + 0.003), new esri.SpatialReference({ wkid: 2271 }));
myExtent = esri.geometry.geographicToWebMercator(myExtent);
var point = new esri.geometry.Point(lon, lat, new esri.SpatialReference({ wkid: 2271 }));
var point_wm = esri.geometry.geographicToWebMercator(point);
var picsymbol = esri.symbol.PictureMarkerSymbol(pic, 33, 40);
var attr = { "XCoord": lon, "YCoord": lat, "Desc": dis };
var infoTemplate1 = new esri.InfoTemplate("Latitude: ${YCoord} <br/>Longitude: ${XCoord}", "POI: <br/>${Desc}");
polygonGraphic = new esri.Graphic(point_wm, picsymbol, attr, infoTemplate1);
map.graphics.add(polygonGraphic);
map.setExtent(myExtent.expand(1.25), true);
}
dojo.addOnLoad(init);
