Swap colors of plots

Question

I want to swap two plot colors in my figure. Please take a look at this:

As you can see, the "short-run" graph is omitted in the second figure. Thus, in order to reduce confusions when studying the two figures, I want to change the color of the "short-run" in figure 1 to brown and of the "long-run" to red. This is my code:

I tried to insert red or brown into the \addplot table [y=ShortRun,col sep=semicolon], as suggested here, but it doesn't change anything. Can anyone help me please figuring out what I'm doing wrong?

Also, is it possible to have these figures side-by-side? I tried to change the size of the whole figure, so that they would fit next to each other, but this doesn't look very good. Maybe there are some other solutions I could try out?

Thanks for the help!

Answer 1

Solution 1: Simply swap the order of plots in the first figure.

\addlegendentry{Long-run}
\end{axis} 
\end{tikzpicture}
\end{figure}
\end{document}

Note that the formating goes in \addplot[], not in ... table [], where + indicates append.

Solution 3: In Figure 2, skip ahead one in the cycle list (the sequence of styles applied to each successive plot). This can be done with \pgfplotsset{cycle list shift=1} as follows.

Also, is it possible to have these figures side-by-side? I tried to change the size of the whole figure, so that they would fit next to each other, but this doesn't look very good. Maybe there are some other solutions I could try out?

Have you seen this question: Two figures side by side?

Likewise, in terms of scaling your plots, there are various options.

The following solution uses minipages for side-by-side figures and resizebox to scale the plots accordingly:
