Hello all. I am new to geocharting and have a question regarding the
ability to geochart multiple measures. I am looking at the geochart
example and it provides a data array that includes population and area by
city and a color axis to describe the data. Can another data array also be
included that includes a different set of cities, a different measure,
let's say median income, and is colored by a different color band?
Below is the sample code provided:
-------------------------------------------------------------------------------------------------------------------------------------------------------------
<html>
<head>
<script type='text/javascript'
src='https://www.google.com/jsapi'></script>
<script type='text/javascript'>
google.load('visualization', '1', {'packages': ['geochart']});
google.setOnLoadCallback(drawMarkersMap);
function drawMarkersMap() {
*var data = google.visualization.arrayToDataTable([*
* ['City', 'Population', 'Area'],*
* ['New York', 2761477, 1285.31],*
* ['Chicago', 1324110, 181.76],*
* ['Los Angeles', 959574, 117.27],*
* ['Miami', 907563, 130.17],*
* ['San Antonio', 655875, 158.9],*
* ['Sacramento', 607906, 243.60],*
* ['Phoenix', 380181, 140.7],*
* ['Philadelphia', 371282, 102.41],*
* ['Bluffton', 67370, 213.44],*
* ['Cleveland', 52192, 43.43],*
* ['Detroit', 38262, 2000]*
* ]);*
var options = {
region: 'US',
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>
</html>
