Hi,
I found an issue when working with the annotatedtimeline-chart and I'm
not sure whether this is a bug or some kind of feature, perhaps you
can help me out?
When I have a datatable with a number of columns and the last column
has no data for any row, the x-axis of the graph will get screwed-up
(no ticks anymore).
Reproducable by pasting the following code in the playground
function drawVisualization() {
var data = new google.visualization.DataTable();
data.addColumn('date', 'Date');
data.addColumn('number', 'Sold Pencils');
data.addColumn('number', 'Sold Pens');
data.addColumn('number', 'Sold Things');
data.addRows([
[new Date(2011,5,5), 7, 12, undefined],
[new Date(2011,5,7), 9, 10, undefined],
[new Date(2011,5,15), 6, undefined, undefined],
[new Date(2011,5,28), 7, 8, 7]]);
var annotatedtimeline = new google.visualization.AnnotatedTimeLine(
document.getElementById('visualization'));
annotatedtimeline.draw(data, {'displayAnnotations': true});
}

Best regards,
