Ups, looks like I should have searched better. I just found this in this forum: https://groups.google.com/forum/?fromgroups=#!searchin/google-visualization-api/annotation$20style$20letter$20line/google-visualization-api/ccLfHm-EhFU/2uMHoJT5TKkJ
I'm still not sure I can implement this using gwt-visualization, but hopefully from the javascript sample above I can figure it out even if I have to use javascript (JSNI). If any of you has already done this on the GWT/Java side, please share your knowledge. Thanks.
