I am trying to modify the font size of some text labels in a pgfplot graph I'm playing around with, but it seems pgfplot doesn't understand certain font sizes such as \normal etc. Yet the pgfplot documentation states

A font can be any LATEX argument like \footnotesize or \small \bfseries

I have created a test-case:

\begin{tikzpicture} 
\begin{axis}[
log ticks with fixed point,
xlabel=x,
ylabel=y,
enlargelimits=0.2
] 

\addplot[only marks, black, mark=triangle*, mark options={fill=white}]
coordinates { 
(0.5, 10)  
(0.6, 20)  
(0.7, 30)
}; 

\node [above] at (axis cs:  0.5,  10) {\small A}; 
\node [above] at (axis cs:  0.6,  20) {\small B}; 
\node [above] at (axis cs: 0.7, 30) {\small B};
\end{axis}
\end{tikzpicture}

I am using LyX as my editor. The following font-sizes throw up an Undefined control sequence error:

\smallest 
\smaller 
\normal 
\larger 
\largest

Am I missing something?

    None of those commands is defined. – egreg Dec 18 '13 at 20:19

    As egreg says, you've missed which commands like that are defined. See e.g. http://tex.stackexchange.com/a/24600/586 for a complete list (for the standard document classes, other classes may define other commands as well). – Torbjørn T. Dec 18 '13 at 21:07

None of the commands

\smallest 
\smaller 
\normal 
\larger 
\largest

is defined in standard LaTeX. The size changing commands are (from the smalles to the largest)

\tiny
\scriptsize
\footnotesize
\small
\normalsize
\large
\Large
\LARGE
\huge
\Huge

The package relsize adds a facility for choosing a font by specifying how many steps from the current size, with \larger and \smaller. Similar commands are defined in the AMS classes (amsart and amsbook).
