I've been playing with Google Map API for a few days now and it's pretty straight forward for the most part, but one thing that we need to do, I can't figure out. I've played with the labels as you can see in the example below, but I'm unable to give them to look that I have in the image below. Can someone point me to a reference so I can achieve my requirements?
If your looking for the makerwithlable.js, you can get it from here.. Its where I got it:

I am using Google Maps API and I have implemented custom circle using this SO answer as reference which is working absolutely fine.
Here below is my screenshot what I have done so far.
As you can see above, I am showing my count with Map Icon.
Now I have used infobox as well so when I click on map icon, its opening something like this.
Now the problem which I am facing if I click on my count, its not opening the same infobox which is opening if I click on my icon.
I tried to use below code inside my for loop but its not working for me.
google.maps.event.addListener(ibLabel, 'click', (function (marker, i) {
return function () {
infowindow.setContent(locations[i][0]);
infowindow.open(map, marker);
}
})(marker, i));
Here is my full source code what I have done so far.
var locations = chartData;
map = new google.maps.Map(document.getElementById('map-canvas'), {
zoom: 4,
center: new google.maps.LatLng(-27.4756261, 129.3748879),
mapTypeId: google.maps.MapTypeId.ROADMAP
});
map.setOptions({minZoom: 1, maxZoom: 15});
var marker, i;
var circle;
var latlng;
var myLatLng;
var closeInfoBox = document.getElementById("close-button");
var infowindow = new google.maps.InfoWindow({maxWidth: 350});
var oms = new OverlappingMarkerSpiderfier(map, {
//markersWontMove: true, // we promise not to move any markers, allowing optimizations
// markersWontHide: true, // we promise not to change visibility of any markers, allowing optimizations
// basicFormatEvents: true // allow the library to skip calculating advanced formatting information
});
for (i = 0; i < locations.length; i++) {
var user_id_array = '<?= $user_id_array; ?>';
var image_name = 'ouvar-pin-new.png';
var get_user_id = locations[i][4];
var fill_color_val = '#154ff6';
var latitude = locations[i][1];
var lontitude = locations[i][2];
myLatLng = google.maps.LatLng(latitude, lontitude);
var latlng = new google.maps.LatLng(latitude, lontitude);

{
var data = JSON.parse(user_id_array);
image_name = data[get_user_id];
if(image_name != 'ouvar-pin-new-blue.png'){
fill_color_val = '#f24e82';
}
// alert(image_name);
}
marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i][1], locations[i][2]),
map: map,
});

return function () {
infowindow.setContent(locations[i][0]);
infowindow.open(map, marker);
}
})(marker, i));
google.maps.event.addListener(marker, 'click', (function (marker, i) {

infowindow.close();
marker.open = false;
});
oms.addMarker(marker);
//oms.addMarker(marker);
}

window.oms = oms;

$('.iw-bottom-gradient').css({display: 'none'});
}
iwCloseBtn.mouseout(function () {
$(this).css({opacity: '1'});
});
});
Can someone guide me how to enable click event for my custom circle as well.
If you want something to happen when someone clicks on the circle, you need to add a click listener to it. The code below will open the same infowindow on a click of the circle as the click listener on the marker (and reference it to the marker).
google.maps.event.addListener(circle, 'click', (function(marker, i) {
return function() {
infowindow.setContent(locations[i][0]);
infowindow.open(map, marker);
}
})(marker, i));

I have two sets of points coordinates that I need to connect on google map, like this, just much larger:
var start = ['42.81405, 12.4886861111', '32.7994444444, 20.506775', '44.8062644989, 20.5005495758'];
var end = ['47.81405, 18.4886861111', '33.7994444444, 21.506775', '39.8062644989, 16.5005495758'];
The first coordinate from "start" needs to be connected to the first coord from "end", and so on, until the end. Got that, but now I need to make "start" and "end" points more recognizable, put some kind of dots in a different color on them. What I have:
var geocoder;
var map;
function initialize() {
var center = new google.maps.LatLng(51.97559, 4.12565);
map = new google.maps.Map(document.getElementById('map'), {
center: center,
zoom: 12,
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var bounds = new google.maps.LatLngBounds();
var start = ['42.81405, 12.4886861111', '32.7994444444, 20.506775', '44.8062644989, 20.5005495758'];
var end = ['47.81405, 18.4886861111', '33.7994444444, 21.506775', '39.8062644989, 16.5005495758'];
var paths = [];
for (var i=0; i < end.length; i++){
var startCoords = start[i].split(",");
var startPt = new google.maps.LatLng(startCoords[0],startCoords[1]);
var endCoords = end[i].split(",");
var endPt = new google.maps.LatLng(endCoords[0],endCoords[1]);
paths.push([startPt, endPt]);
bounds.extend(startPt);
bounds.extend(endPt);
}
map.fitBounds(bounds);
var polyline = new google.maps.Polygon({
paths: paths,
strokeColor: 'red',
strokeWeight: 2,
strokeOpacity: 1
});
polyline.setMap(map);
}
google.maps.event.addDomListener(window, "load", initialize);
Any kind of help is welcomed.
The simplest thing you can just create markers for start and end points. Like the following code
for (var i=0; i < end.length; i++){
var startCoords = start[i].split(",");
var startPt = new google.maps.LatLng(startCoords[0],startCoords[1]);
var endCoords = end[i].split(",");
var endPt = new google.maps.LatLng(endCoords[0],endCoords[1]);
paths.push([startPt, endPt]);
bounds.extend(startPt);
bounds.extend(endPt);
//Create start and end markers
var markerStart = new google.maps.Marker({
position: startPt,
icon: {
path: google.maps.SymbolPath.CIRCLE,
scale: 3,
fillColor: 'blue',
strokeColor: 'blue'
},
draggable: true,
map: map
});
var markerEnd = new google.maps.Marker({
position: endPt,
icon: {
path: google.maps.SymbolPath.CIRCLE,
scale: 3,
fillColor: 'green',
strokeColor: 'green'
},
draggable: true,
map: map
});
}
It will give you something like
Code snippet
var map;
function initMap() {
var center = new google.maps.LatLng(51.97559, 4.12565);
map = new google.maps.Map(document.getElementById('map'), {

I am dealing with an unusual problem. I am using google map API for drawing Polygons in the maps. My problem is that only the first one Polygon is working normally and firing event "click" works.
Here is my code, if you run the code snippet that you will see that only the first polygon is working normally the event click does not work on the others.
var map;
var infoWindow;
var listOfPolygons = [];
function initMap() {
map = new google.maps.Map(document.getElementById('map'), {
zoom: 5,
center: {lat: 24.886, lng: -70.268},

},

circleOptions: {
fillColor: '#ffff00',
fillOpacity: 1,
strokeWeight: 5,
clickable: false,
editable: true,
zIndex: 1
}
});
drawingManager.setMap(map);
google.maps.event.addListener(drawingManager, 'overlaycomplete', function(event) {
if (event.type == 'polygon') {
alert("Polygon Completed");
listOfPolygons.push(new google.maps.Polygon({
paths: event.overlay.getPath().getArray(),
strokeColor: '#FF0000',
strokeOpacity: 0.8,
strokeWeight: 3,
fillColor: '#FF0000',
fillOpacity: 0.35
}));
listOfPolygons[listOfPolygons.length - 1].setMap(map);
listOfPolygons[listOfPolygons.length - 1].addListener('click', showArrays);
alert(listOfPolygons.length);
}
});
infoWindow = new google.maps.InfoWindow();
}
/** #this {google.maps.Polygon} */
function showArrays(event) {
// Since this polygon has only one path, we can call getPath() to return the
// MVCArray of LatLngs.
var vertices = this.getPath();
var contentString = '<b>Bermuda Triangle polygon</b><br>' +
'Clicked location: <br>' + event.latLng.lat() + ',' + event.latLng.lng() +
'<br>';
// Iterate over the vertices.
for (var i =0; i < vertices.getLength(); i++) {
var xy = vertices.getAt(i);
contentString += '<br>' + 'Coordinate ' + i + ':<br>' + xy.lat() + ',' +
xy.lng();
}
// Replace the info window's content and position.
infoWindow.setContent(contentString);
infoWindow.setPosition(event.latLng);
infoWindow.open(map);

The polygon from the DrawingManager is on top of the Polygon with the click listener. You only want one version of the new Polygon, the one with the click listener added to it, hide the one from the DrawingManager (inside the overlaycomplete listener):
google.maps.event.addListener(drawingManager, 'overlaycomplete', function(event) {
if (event.type == 'polygon') {
// hide polygon from DrawingManager
event.overlay.setMap(null);
// ....... existing code ............

I use this code to create my markers (TypeScript btw)
The options for the icon allows me to rotate and set a fill color of the marker.
But how can I change the fill color and rotation after creation?
I have found various responses here on SO, but they refer to changing the icon to a bitmap and swap between red and green bitmaps for example.
Which is not what I want.
var icon = {
path: google.maps.SymbolPath.FORWARD_CLOSED_ARROW,
scale: 4,
fillColor: "#ff5050", //<-- I want to change this after creation
fillOpacity: 1,
strokeWeight: 1,
rotation: 0 //<-- I want to change this after creation
};
var markerOptions = <google.maps.MarkerOptions>{
map: this.map,
icon: icon,
};
Anyone know?
Calling .setIcon on the marker works for me:
setInterval(function () {
angle += 30;
cnt++;
icon.rotation = angle;
icon.fillColor = colorArray[cnt % colorArray.length]
marker.setIcon(icon);
}, 1000);

This question already has an answer here:
How do I fade out a circle in a Google Map, x seconds after I've added it to the map?
(1 answer)
Closed 8 years ago.
I am attempting to fade circles out with a setInterval on fillOpacity. However a console log shows the opacity changing but the appearance of the circle does not seem to change. Is there a different set function required to do this?
http://jsfiddle.net/faaxeskg/5/
setInterval(function() {
marker.fillOpacity -= .01;
console.log(marker.fillOpacity);
}, 200);
code snippet:
var map = null;
function initialize() {
var mapOptions = {
zoom: 4,
center: new google.maps.LatLng(-25.363882, 131.044922)
};
map = new google.maps.Map(document.getElementById('map-canvas'),
mapOptions);
// Add 500 markers to the map at random locations
var southWest = new google.maps.LatLng(-31.203405, 125.244141);
var northEast = new google.maps.LatLng(-25.363882, 131.044922);
var bounds = new google.maps.LatLngBounds(southWest, northEast);
map.fitBounds(bounds);
var lngSpan = northEast.lng() - southWest.lng();
var latSpan = northEast.lat() - southWest.lat();
setInterval(function() {
var position = new google.maps.LatLng(
southWest.lat() + latSpan * Math.random(),
southWest.lng() + lngSpan * Math.random());
var populationOptions = {
strokeOpacity: 0,
fillColor: '#FF0000',
fillOpacity: 0.65,
map: map,
center: position,
radius: 40000
};
var marker = new google.maps.Circle(populationOptions);
setInterval(function() {
marker.fillOpacity -= .01;
console.log(marker.fillOpacity);
}, 200);
setTimeout(function() {
marker.setMap(null);
delete marker;
}, 30000);
}, 2000);
}
google.maps.event.addDomListener(window, 'load', initialize);

You need to associate the "opacity change" to the marker, you can do that with function closure (a createCircleMarker function).
Don't use undocumented properties. Use the documented methods.
marker.set("fillOpacity, marker.get("fillOpacity")-0.01);
working code snippet:
var map = null;
function initialize() {
var mapOptions = {
zoom: 4,
center: new google.maps.LatLng(-25.363882, 131.044922)
};
map = new google.maps.Map(document.getElementById('map-canvas'),
mapOptions);
// Add 500 markers to the map at random locations
var southWest = new google.maps.LatLng(-31.203405, 125.244141);
var northEast = new google.maps.LatLng(-25.363882, 131.044922);
var bounds = new google.maps.LatLngBounds(southWest, northEast);
map.fitBounds(bounds);
var lngSpan = northEast.lng() - southWest.lng();
var latSpan = northEast.lat() - southWest.lat();
setInterval(function() {
var position = new google.maps.LatLng(
southWest.lat() + latSpan * Math.random(),
southWest.lng() + lngSpan * Math.random());

}, 2000);
