How do I add numbers on top of my bar graph (google chats)

H

I want to add numbers a top a bar graph using the goole chart api

what I want

That is what I want. It is an example from the home page. When 开发者_开发百科I look at the options for bar charts I don't see it. I am not sure what it would be called but nothing I see looks like it(at least not from the example pictures).

The "|N,FF0000,-1,-1,10" on the above URL is the magic sauce that makes it work.

The Text and Data Value Markers documentation explains:

chm=<marker_type>,<color>,<series_index>,<opt_which_points>,<size>,<opt_z_order>,<opt_placement>.

Where <marker_type> in this case, is N.
