I am trying to implement an Annotated Time Line Chart via Google Charts API. I successfully got it work, using an AJAX call to load data from a database, however I noticed that although the annotations appear on the right, they would not appear above the points on the graph ( like tool-tips). However they worked great otherwise, I could click on them and even include the Annotation filter properly.
After an hour or so of not seeing any errors, I decided to go back to the drawing board and took an exact copy of the chart example code from the Google API and test it out. It turns out I am having the same issue.
The link to the tutorial is here (notice how A and B show up on the graph itself), I also pasted the code below.
Is there some setting I'm missing or something that would be blocking this? I tested in Chrome and Firefox and neither worked. Also it works for me on the tutorial page so I'm at a loss.

Reset to default 7My guess is that you are using https://www.google./jsapi instead of http://... but your page is not in https.
And a ment... You are using a mix of quotes and double quotes, that's not very clean.
Try to stick to a simple rule like: Keep the double quotes for HTML like id="chart_div" and the single quote for Javascript data.addColumn('date', 'Date');.
I had the same problem as you when I was viewing my chart from file:// but when I uploaded it to a server and tested it at http:// the annotation markers showed up on the timeline like they are supposed to.
