Chart marker/flag

[amirmiller]

Hi,

I am not sure what the proper term is so i'll try to describe what I'm
looking for.
I am displaying a chart of bug trends and I would like to draw a line
or flag or some kind of marker which represent special days in the
project's life cycle such as Code freeze, Release etc.
Kind of like the Dividend marker on this chart from Yahoo Finance:
http://finance.yahoo.com/echarts?s=TEVA+Interactive#chart6:symbol=teva;range=6m;indicator=split+dividend+volume;charttype=line;crosshair=on;ohlcvalues=0;logscale=on;source=undefined

Hope someone can point me to the proper API.
Thanks,

Amir.

Annotated Timeline charts (http://code.google.com/apis/chart/interactive/docs/gallery/annotatedtimeline.html) are probably what you are looking for (Flash required).

Isn't there a way to put an annotation on other charts?
The timeline chart doesn't fit my other requirements.

No, there isn't a way to add annotations to an other charts.  The closest you can get to that functionality is the tooltips.

I spoke too soon.  According to the new release candidate news, Line and Area charts now support annotations (use version 1.1 instead of 1.0 when calling google.load() to load the RC instead of the production version).

Talking more often?  Don't I open my fat mouth around here often enough?  >;o)~

Unfortunately it does not provide any clue as to how to code these
annotations.
I tried adding 'displayAnnotations': true to my definition but that
didn't work.

Hope they will update their docs soon.

The examples posted have the structure for the annotations (view the source and look at the chart drawing functions).  Basically, add 2 extra DataTable columns after each data column that you want to annotate, passing an object in the new format {type: 'data type', role: 'column role'} with type 'string' and roles 'annotation' and 'annotationText'.  The 'annotation' column contains the labels that appear on the chart while the 'annotationText' column contains the annotations' tooltip text.  I pulled the annotation example from those posted by the chart team and put them on jsfiddle to make it easy to see them in action along side the code: http://jsfiddle.net/9P8XF/1/
