Is there any way to show only a specific country or region using the google maps API?
回答1:
It can be done using GeoMap API. Please check following url for reference.
1) https://code.google.com/apis/ajax/playground/?type=visualization#geo_map
2) https://developers.google.com/chart/interactive/docs/gallery/geomap#regionsexample
Here is the example to load US region map.
<html>
<head>
<script type='text/javascript' src='https://www.google.com/jsapi'></script>
<script type='text/javascript'>
google.load('visualization', '1', { 'packages': ['geomap'] });
google.setOnLoadCallback(drawMap);
function drawMap() {
var data = google.visualization.arrayToDataTable([
['City', 'Popularity'],
['New York', 200],
['Boston', 300],
['Miami', 400],
['Chicago', 500],
['Los Angeles', 600],
['Houston', 700]
]);
var options = {};
options['region'] = 'US';
options['colors'] = [0xFF8747, 0xFFB581, 0xc06000]; //orange colors
options['dataMode'] = 'markers';
options['width'] = '556px';
var container = document.getElementById('map_canvas');
var geomap = new google.visualization.GeoMap(container);
geomap.draw(data, options);
};
</script>
</head>
<body>
<div id='map_canvas'></div>
</body>
</html>
