[Tex/LaTex] Change axis number format for external tikz file

Question

I'm using \input{filename.tikz} to include .tikz graphs created by matlab2tikz in my LaTeX document. As shown in a comment on this question it is possible to change the plot marker size when the document is inputted, without altering the original .tikz file.

Now I'm looking for a way to change the axis number formatting in the same fashion.
I have numbers on the y-axis that are of the form 5 x 10^-2 where I want them just to be 0.05.

I understand from this answer that this has more to do with pgfplot than with tikz, but I'm not sure how I would use the command given in the answer right before my \input statement.

Answer 1

The keys given in the axis options can also be set outside the axis environment by using

\pgfplotsset{
    every x tick label/.append style  =
        { 
          /pgf/number format/.cd,
           precision = 0, 
           fixed
        }
}

or, equivalently

\pgfkeys{
    /pgfplots/every x tick label/.append style  =
        { 
          /pgf/number format/.cd,
           precision = 0, 
           fixed
        }
}

For the example given in the answer this would become:

\pgfkeys{
        /pgfplots/every y tick label/.append style  =
            { 
              /pgf/number format/.cd,
               precision = 2, 
               fixed
            }
    }
