I'm creating graphs in pgf/tikz. When I use these in my document they are scaled, several are in minipage/subfig like environments. When this happens the font sizes are scaled with the graphics making them very small or unreadable. I've been through the manual but have so far been unsuccessful in my attempts to control this.
Is there a way to set the font size directly? What options are there?
One aswer given below shows how to how to use the \tikzstyle font option to specify the font size within the tikzpicture environment.
Right now I am using:
\beginppgfgraphicnamed{graph}
\input{graph.tex}
\endpgfgraphicnamed
The tikzpicture environment is used in the input file. Are there anyways to specify font size in the setup I'm using? Is this perhaps the issue? The graph.tex file is generated automatically via another program.
In addition to setting font size for individual graphics it would be ideal to have a parameter to globally set font size for all tikz graphics? I guess the issue is the scaling in minipage or subfig.
Many thanks,
Jay
\begin{tikzpicture}
\tikzstyle{every node}=[font=\small]
\end{tikzpicture}
will give you font size control on every node.
