I am trying to define my tizk shape style in a way that I can enter a text under the shape as a comment!
For example in the uploaded picture, (2 min) is the comment I am talking about. Is there a way to do that? Ideally, I'd like to define the properties of this commnet in the \tikzstyle, so that I can easily use it in my shape.
sample \tikzstyle:
\tikzstyle{block} = [
rectangle, draw,
fill=blue!20,
text width=7em,
text centered
]

label=270:(2min)to your options or make a variable. – percusse Dec 30 '12 at 18:54label=below:(2min)would be more intuitive? – Jake Dec 30 '12 at 18:58270option you have to remember that the angle starts on the right and counts counter-clockwise, to arrive at the bottom of the node at an angle of270degrees. Personally, I findbelowmakes more sense when you want to position something below a node. – Jake Dec 30 '12 at 19:04below,above,left,rightetc. such that one does not try to shift the label manually. – percusse Dec 30 '12 at 19:08
