In my case, the value in 'data.dat' is all nan.

\addplot table [
        x=X,
        y=value
    ] {data.dat};
    \addlegendentry{{\scriptsize small city}}

So in the legend, there is no entry for this table. But I still want to generate one. How should I customize it? Thanks!

You could use the \addlegendimage macro from the accepted answer in http://tex.stackexchange.com/questions/54794/using-a-pgfplots-style-legend-in-a-plain-old-tikzpicture – John Kormylo Jul 15 '16 at 13:32
