Hi All,
I have the following snipped that's producing the above error and the chart
doesn't render. I'm new to JS and gViz API as well. What am I doing wrong?
<table>
<h1>Software Versions - By Role</h1>
<div id="chart_div"></div>
<script type="text/javascript">
google.load("visualization", "1", {packages:["corechart"]});
google.setOnLoadCallback(drawChart);
function drawChart(){
// Create DataTable object from dremel table
var dt = new google.visualization.DataTable();
dt.addColumn('string', 'name');
dt.addColumn('string', 'role');
dt.addColumn('string', 'vendor');
dt.addColumn('string', 'hw_rev');
dt.addColumn('string', 'sw_rev');
// Populate with data from Dremel query
dt.addRow(['ar01.bog01',
'AR',
'Juniper',
'mx960',
'13.3X2'
]);
dt.addRow(['ar01.bom05',
'AR',
'Juniper',
't4000',
'13.3X2'
]);
dt.addRow(['ar01.bom07',
'AR',
'Juniper',
't4000',
'13.3X2'
]);
dt.addRow(['ar01.ctg01',
'AR',
'Juniper',
'mx960',
'13.3X2'
]);
// More entries omitted
var chart = new google.visualization.Histogram(
document.getElementById('chart_div'));
var column_key = [1, 2];
//var column_opt = [1, {'column':2,
'aggregation':google.visualization.data.count, 'type':'number'}];
var chart_opts = {
title: 'Sofware Revsions by Role',
}
var group = google.visualization.data.group(
dt,
column_key
);
chart.draw(group);
}
</script>
</table>
