我使用了arraytodatatable
并试图在地图上显示我的数据,但是我在地图上没有看到任何标记。
这是我使用的代码
<html>
<head>
<title>Google Charts Tutorial</title>
<script type = "text/javascript" src =
"https://www.gstatic.com/charts/loader.js"></script>
<script type = "text/javascript" src =
"https://www.google.com/jsapi"></script>
<script type = "text/javascript">
google.charts.load('current', {packages: ['map'],'mapsApiKey': 'my
API'});
</script>
</head>
<body>
<div id = "container" style = "width: 550px; height: 400px; margin:
0
auto">
</div>
<script language = "JavaScript">
function drawChart() {
// Define the chart to be drawn.
var data = google.visualization.arrayToDataTable([
['Lat', 'Long', 'Name'],
[37.4232, -122.0853, 'Work'],
[37.4289, -122.1697, 'University'],
[37.6153, -122.3900, 'Airport'],
[37.4422, -122.1731, 'Shopping']
]);
// Set chart options
var options = {
showTip: true,
};
// Instantiate and draw the chart.
var chart = new
google.visualization.Map(document.getElementById('container'));
chart.draw(data, options);
}
google.charts.setOnLoadCallback(drawChart);
</script>
</body>
</html>
我收到的错误消息是:
maps.google.com/mapfiles/ms/micons/red-dot.png:1 GET
file://maps.google.com/mapfiles/ms/micons/red-dot.png
net::ERR_FILE_NOT_FOUND
这是否意味着不再使用标记的图像?如果是这样,我是否可以更改标记的颜色,以便解决问题?
