I'm trying to output the following data to the screen as both a table
and a chart. When I try this, I get the table fine, but the Chart
appears without any bars (the y-axis goes from 0 to 1 without any bars
in the graph). Is there something I'm doing wrong when trying to
output the chart?
<script type="text/javascript" src="http://www.google.com/jsapi";></
script>
<script type="text/javascript">
google.load('visualization', '1', {packages: ['table']});
google.load('visualization', '1', {packages: ['columnchart']});
</script>
<script type="text/javascript">
function drawVisualization() {
// Create and populate the data table.
var JSONObject = {cols: [{id: 'ActivityDate', label:
'ActivityDate', type: 'string'},{id: 'Count', label: 'Count', type:
'number'}], rows: [{c: [{v: 'DateA'},{v: '130'}]},{c: [{v: 'DateB'},
{v: '255'}]},{c: [{v: 'DateC'},{v: '380'}]}]};
var data = new google.visualization.DataTable(JSONObject);
// Create and draw the visualization.
visualization = new google.visualization.Table
(document.getElementById('table'));
visualization.draw(data, null);
// Create and draw the visualization.
new google.visualization.ColumnChart(document.getElementById
('chart_div')).
draw(data, null);
}
google.setOnLoadCallback(drawVisualization);
</script>
Thanks!
