is it possible to have multiple google charts in one page?
Question
I am using Google visualization api. Following is my sample code. Either of the two charts can be shown if it is the only one to be drawn. But I can not get both working. Thanks for your advice.
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"></meta>
<title>Home Page</title>
<!--Load the AJAX API-->
<script type="text/javascript" src="http://www.google.com/jsapi"></script>
<script type="text/javascript">
//Load the Visualization API and the ready-made Google table visualization
google.load('visualization', '1', {'packages':['corechart']});
</script>
<script type='text/javascript'>
function drawA() {
// Define the chart using setters:
var wrap = new google.visualization.ChartWrapper();
wrap.setChartType('ColumnChart');
wrap.setDataSourceUrl('dataurl');
wrap.setContainerId('checkin-column');
wrap.setOptions({'title':'Daily Check-in Numbers', 'width':500,'height':400});
wrap.draw();
wrap.getChart();
}
function drawB() {
// Define the chart using setters:
var wrap = new google.visualization.ChartWrapper();
wrap.setChartType('ColumnChart');
wrap.setDataSourceUrl('dataurl2');
wrap.setContainerId('redemption-table');
wrap.setOptions({'title':'Redemption History', 'width':500,'height':400});
wrap.draw();
}
function drawVisualization() {
drawA();
drawB();
}
google.setOnLoadCallback(drawVisualization);
</script>
</head>
<body>
<div id="checkin-column"/>
<p/>
<div id="redemption-table"/>
</body>
</html>

The problem is in your divs.
Replace this:
<div id="checkin-column"/>
<p/>
<div id="redemption-table"/>
With this:
<div id="checkin-column"></div>
<p></p>
<div id="redemption-table"></div>

Just throwing down some information that relates to a problem I had (not the OP's exact Q).
When you want to draw multiple charts on one page, you must use different ids for the divs your targeting (duh.), So if you have a page that should have multiple charts but only 1 (or N < expected) is rendering. double check that there is a unique div id for each chart and that the JavaScript targets a unique div id.
Eg, the following will render only one chart:
<div id="chart"></div>
<script type="text/javascript" src="http://www.google.com/jsapi"></script>
<script type="text/javascript">
google.load('visualization', '1', {packages: ['corechart']});
google.setOnLoadCallback(drawChart);
google.setOnLoadCallback(drawChart2);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['', 'Stuff', 'Stuff2'],
['', 1.0, 2.0]
]);
var options = {
title: 'MyChart',
pointSize: 3,
vAxis: {
baseline: 0.1,
title: 'vAxis'
},
hAxis: {
title: 'hAxis'
}
};
var chart = new google.visualization.ColumnChart(document.getElementById('chart'));
chart.draw(data, options);
}
function drawChart2() {
var data = google.visualization.arrayToDataTable([
['', 'Stuff', 'Stuff2'],
['', 4.0, 5.0]
]);
var options = {
title: 'MyChart2',
pointSize: 3,
vAxis: {
baseline: 0.1,
title: 'vAxis'
},
hAxis: {
title: 'hAxis'
}
};
var chart = new google.visualization.ColumnChart(document.getElementById('chart'));
chart.draw(data, options);
}
</script>

Probably not your problem, but on a related note, I have found that if you have lots of Google Visualizations on the same page ( I believe that it was in the neighborhood of 50), Google will throttle the usage, and stop rendering properly.
