I'm working on a project where I have a need to draw a map with a little over 500 points on it. The code I have works well up to 250 points. But when I have all 500 coordinates in the XML file that it parses, no points end up displaying on the map.
I imagine there is some kind of throttling that is causing it to fail but I can't figure out how to include this in the code.
Any ideas?

My guess is there is a problem with your data somewhere around the 250th entry.

Hi I've been working on this realtime gps tracker but I can't get beyond an error, I think it has something to do with making "map" a global variable .
What happens is, I am using gps cordinates that are loaded via ajax from an xml file and parsed into an array, but it seems I can't display the markers.

I am a beginner at google maps.
I am trying to toggle google map markers based on there type.
When I unchecked the check-box the marker disappears and upon checking it again the markers do not appears back on the map.
I have tried changing setmap to setvisible in toggleGroup function but that also did not worked .

Your issue:
You are mixing 2 different things here: getMap() and getVisible().
How to use:
To render a marker on the map, use:
marker.setMap(map); // where "map" is your map instance
To remove a marker from the map:
marker.setMap(null);
To show a hidden marker:
marker.setVisible(true);
To hide a marker:
marker.setVisible(false);
How to fix:
You should adapt your toggleGroup function accordingly.
Details:
marker.setMap(null);
marker.setVisible(true); // marker will not be shown since it's not on the map anymore
I have a page that a user inputs markers on a google map and it saves the center of map latitude and longitude, zoom and the latitude and longitude of the marker into MySQL. Next I'm trying to have a page that displays all the different maps a user has saved with the markers. I have searched and all I can find is how to display multiple markers on the same map or a set number of maps on the same page with a set lat and long.
Could anybody suggest where to start with this or a tutorial on this.
Here is the code I've started with that displays one google map with all the markers that have been entered. Not familiar with javascript, so need pointed in the right direction.
Thanks

Thank you all in advance
You create markers like
var marker = new google.maps.Marker({
position: myLatlng,
title:"Your title"
});
create links which on click trigger
infowindow.open(map,marker);
thats all i guess.
EDIT: You could identify which marker needs to be shown by href-parameter
Very strange. When I preview the file for my map on my local computer, it works just fine and the marker appears. However, when I upload to my web server, the marker disappears. The files are exactly the same...
Does anyone know what's going on?

It works for me in Chrome, Firefox and IE8. Perhaps you have a bad copy of the xml stuck in the browser cache (which browser are you using?)
Try using your own legitimate key. This line
<script src="http://maps.google.com/maps/api/js?sensor=false"
type="text/javascript"></script>
should look something more like this
<script type="text/javascript"
src="http://maps.googleapis.com/maps/api/js?key=AacbdefglcdK7C2GHbQAmdkBID70Uppuf-D030&sensor=true">
</script>
You can apply for your own Google Maps API key on their home page. There are a few reasons why regular users are not allowed to publish using a default Google key because of situations concerning bandwidth, etc. Thus , companies with high volume have to pay to have a license for a Google Maps key, but for your use, a free key will probably work fine.
