Dear All,
I require your assistance in the following:
Below is a sample code gratefully offered by Google in how to create a dot
map charts where the dot markers are referred as 'city'
my question is, if I want to add a city (that i have its coordinates) not
recognized/implemented in Google API inside the array , how am I able to
do so? (ease of reference I added the arrow on the line that I wish to
implement)
<html>
<head>
<script type='text/javascript'
src='https://www.gstatic.com/charts/loader.js'></script>
<script type='text/javascript'>
google.charts.load('current', {
'packages': ['geochart'],
// Note: you will need to get a mapsApiKey for your project.
// See:
https://developers.google.com/chart/interactive/docs/basic_load_libs#load-settings
'mapsApiKey': 'AIzaSyD-9tSrke72PouQMnMX-a7eZSW0jkFMBWY'
});
google.charts.setOnLoadCallback(drawMarkersMap);
function drawMarkersMap() {
var data = google.visualization.arrayToDataTable([
['City', 'Population', 'Area'],
['Rome', 2761477, 1285.31],
['Milan', 1324110, 181.76],
['Naples', 959574, 117.27],
['Turin', 907563, 130.17],
['Palermo', 655875, 158.9],
['Genoa', 607906, 243.60],
['Bologna', 380181, 140.7],
['Florence', 371282, 102.41],
['Fiumicino', 67370, 213.44],
['Anzio', 52192, 43.43],
['Ciampino', 38262, 11],
====> [ 'Adding NEW CITY with Latitude Longitude", 55555, 100]
]);
var options = {
region: 'IT',
*displayMode: 'markers',*
colorAxis: {colors: ['green', 'blue']}
};
var chart = new
google.visualization.GeoChart(document.getElementById('chart_div'));
chart.draw(data, options);
};
</script>
</head>
<body>
<div id="chart_div" style="width: 900px; height: 500px;"></div>
</body>
