Hi,
I am strugling with this again. I had a lok at your suggestion
regarding the DataView, but I think the problem is more specific and
not solved with the dataview:
Imagine, I draw the number of sold Pencils and the number of sold Pens
(from the example below). For June 7th I do not know the number of
sold pens -for some reason-. When I draw the following graph and hover
my mouse on the graph around June 7th, you will notice that the legend
will not update correct. Is there a workaround for this?
Thanx,
Erik
function drawVisualization() {
var data = new google.visualization.DataTable();
data.addColumn('date', 'Date');
data.addColumn('number', 'Sold Pencils');
data.addColumn('number', 'Sold Pens');
data.addRows([
[new Date(2011,5,5), 7, 12],
[new Date(2011,5,6), 9, 10],
[new Date(2011,5,7), 6, undefined],
[new Date(2011,5,8), 7, 8]]);
var annotatedtimeline = new google.visualization.AnnotatedTimeLine(
document.getElementById('visualization'));
annotatedtimeline.draw(data, {'displayAnnotations': true});
}
