Hello,
I am trying to display some charts in a tabbed Window in Joomla. That works
fine. Here is the code of one of the example-Charts:
<script type="text/javascript">
// Load the Visualization API and the piechart package.
google.load('visualization', '1.0', {'packages':['corechart']});
// Set a callback to run when the Google Visualization API is
loaded.
google.setOnLoadCallback(drawChart);
// Callback that creates and populates a data table,
// instantiates the pie chart, passes in the data and
// draws it.
function drawChart() {
// Create the data table.
var data = new google.visualization.DataTable();
data.addColumn('string', 'Topping');
data.addColumn('number', 'Slices');
data.addRows([
['Mushrooms', 3],
['Onions', 1],
['Olives', 1],
['Zucchini', 1],
['Pepperoni', 2]
]);
// Set chart options
var options = {'title':'Verteilung',
'width':600,
'height':450, is3D: true};
// Instantiate and draw our chart, passing in some options.
var chart = new google.visualization.PieChart(document.
getElementById('chart_div'));
chart.draw(data, options);
}
</script>
It works fine this way. But I want the chart to be displayed after a button
was clicked. I tried it this way:
<script type="text/javascript">
function chart1() {
// Load the Visualization API and the piechart package.
google.load('visualization', '1.0', {'packages':['corechart']});
// Set a callback to run when the Google Visualization API is
loaded.
google.setOnLoadCallback(drawChart);
// Callback that creates and populates a data table,
// instantiates the pie chart, passes in the data and
// draws it.
}
--->>>...anything else stays like before
But it doesn´t work. Where is the mistake?
Thanks for your help.
Sebastian
