Thanks for your comments.
Here is how you should use annotations
function drawVisualization() {
var data = new google.visualization.DataTable();
data.addColumn('date', 'Date');
data.addColumn('number', 'Sold Pencils');
data.addColumn('string', 'title');
data.addColumn('string', 'text');
data.addRows(2);
data.setValue(0, 0, new Date(2008, 1 ,1));
data.setValue(0, 1, 30000);
data.setValue(0, 2, 'aaaa')
data.setValue(0, 3, 'bbbb')
data.setValue(1, 0, new Date(2008, 1 ,2));
data.setValue(1, 1, 14045, 'aaaa');
data.setValue(1, 2, 'cccc')
data.setValue(1, 3, 'dddd')
var annotatedtimeline = new google.visualization.AnnotatedTimeLine(
document.getElementById('visualization'));
annotatedtimeline.draw(data, {'displayAnnotations': true});
}
As for the custom properties of any data table entity (row, column or cell).
They are for your own use, you can tag any entity with additional
information and later use it.
The chart will not use the custom property you set unless declared
otherwise.
