我想用Google Fusion Tables和Javascript製作熱圖。 This is what I made so far in JSfiddle。在熱圖+融合表中自定義半徑和顏色
function initialize() {
var style = [
{
featureType: 'all',
elementType: 'all',
stylers: [
{ saturation: -99 }
]
},
{
featureType: 'road.highway',
elementType: 'all',
stylers: [
{ visibility: 'off' }
]
},
{
featureType: 'road.arterial',
elementType: 'all',
stylers: [
{ visibility: 'off' }
]
},
{
featureType: 'road.local',
elementType: 'all',
stylers: [
{ visibility: 'off' }
]
},
{
featureType: 'administrative.country',
elementType: 'all',
stylers: [
{ visibility: 'off' }
]
},
{
featureType: 'administrative.province',
elementType: 'all',
stylers: [
{ visibility: 'off' }
]
},
{
featureType: 'administrative.locality',
elementType: 'all',
stylers: [
{ visibility: 'off' }
]
},
{
featureType: 'administrative.neighborhood',
elementType: 'all',
stylers: [
{ visibility: 'off' }
]
},
{
featureType: 'administrative.land_parcel',
elementType: 'all',
stylers: [
{ visibility: 'off' }
]
},
{
featureType: 'poi',
elementType: 'all',
stylers: [
{ visibility: 'off' }
]
},
{
featureType: 'transit',
elementType: 'all',
stylers: [
{ visibility: 'off' }
]
}
];
var styledMapType = new google.maps.StyledMapType(style, {
map: map,
name: 'Styled Map'
});
var map = new google.maps.Map(document.getElementById('map-canvas'), {
center: new google.maps.LatLng(52.04843154112624, 5.33935546875),
zoom: 7,
mapTypeControl: false,
streetViewControl: false,
zoomControl: true,
panControl: true,
draggable: true,
zoomControlOptions: {
style: google.maps.ZoomControlStyle.SMALL
},
mapTypeId: google.maps.MapTypeId.ROADMAP
});
map.mapTypes.set('map-style', styledMapType);
map.setMapTypeId('map-style');
layerl0 = new google.maps.FusionTablesLayer({
query: {
select: "'Latitude'",
from: '1nQx1w96dl8YNE_LMnA4Npyrapeo6fErmRXRmB9w'
},
heatmap: {enabled: true},
map: map
});
}
google.maps.event.addDomListener(window, 'load', initialize);
現在我想自定義熱圖的半徑和顏色。 Here's some explanation on the API,但我無法弄清楚它應該如何在代碼中實現。誰能幫助我?
數據量不應該是一個問題,我猜。但是,您如何定製可視化? –
