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
I believe Mica's way deserves the rank of answer, since is not visible enough as a comment:
\begin{tikzpicture}[font=\small]
\begin{tikzpicture}
\tikzstyle{every node}=[font=\fontsize{30}{30}\selectfont]
\end{tikzpicture}
I found the better control would be using scalefnt package:
\usepackage{scalefnt}
...
{\scalefont{0.5}
\begin{tikzpicture}
...
\end{tikzpicture}
}
You can also use:
\usepackage{anyfontsize}
The huge advantage of the anyfontsize
package over scalefnt
is that one does not need to enclose the entire {tikzpicture}
with a \scalefont
environment.
Just adding \usepackage{anyfontsize}
to the preamble is all that is required for the font scaling magic to happen.
