How to make subfigures with different sizes look matching

Question

I have another question concerning tkzpictures.

Currently, my figure looks like this:

It was generated using the following code with the help of pgfplots: two y-axis with three plots and one legend

Now, I would like to have bars for A and B in the legend as it is normally the case with bars. Moreover, I would like to make the bars of subfigures 2 and 3 thicker and enlarge the fonts of the axis titles and numbers, so that the lower subfigures better match the upper one.

Who can help me? Thanks in advance! :)

I think you know the drill: don't provide a code fragment; instead, provide a Minimum Working Example that compiles. Don't make us guess as to which packages need to be loaded in order to get your code to compile. People here would rather tinker with compilable code that engage in guess work. — Mico, Nov 29 '16 at 22:08

Partial answer for others to complete as I don't have more time.

I placed some common options in pgfplotsset
All the fonts and bars are now the same size
Added bar entry to the legend using \addlegendimage{empty legend}\addlegendentry{\ref{a} A}, although it is not perfect yet
