I am sorry, that was copied from an old source. I have the AJAX load
working now:
var jsonData = $.ajax({
url:
"data/testbiertje2/testbiertje2-2011-09-29.json",
dataType:"json",
async: false
}).responseText;
evalledJsonData = eval("("+jsonData+")");
beerData = new
google.visualization.DataTable(evalledJsonData);
beerChart = new
google.visualization.AnnotatedTimeLine(document.getElementById('visualization'));
beerChart.draw(beerData, {
'displayAnnotations': true,
'scaleType': 'maximized',
'displayZoomButtons': false,
'allValuesSuffix': "\u00B0 C",
'numberFormats': "##.0",
'displayAnnotationsFilter' : true});
}
How would I join multiple of these json files?
