Annotated time line is a google visualization library written in flash. I would like to place a div on top of it at times to cover it. However, when I do this, the div covers everything but the annotated time line shows through. What is the problem and how can it be resolved?
You're dealing with flash on the annotated timeline. Set wmode (window mode) to transparent (think oqaque works to) on annotated time line
annotatedtimeline = new google.visualization.AnnotatedTimeLine(
document.getElementById('timespan_chart'));
annotatedtimeline.draw(data, {wmode: 'transparent', ...});
