How to separate a column bar plot with a differente scale in the same figure?

Question

I have been trying to plot some column bars but some results are overwhelming and make the other disappear from the plot. Is it possible to separate those values in another plot next to the other one?

My code is :

\begin{figure}[h]
\centering
\pgfplotsset{compat=1.16}
\begin{tikzpicture}
    \begin{axis}[legend pos=outer north east,
        width=12cm,

        symbolic x coords={A,B,C,D,E},
        xtick={A,B,C,D,E},
        xticklabels={10,7.5,5.2,3.8,3.0},
        ylabel=Size (d.nm),
        enlarge x limits={0.2},
        ymin=0,
        ymode=log,
        ymajorgrids=true,
        scaled ticks=false,

As you can see the last one is pretty big respect to the others thanks!!

There are errors in your code: if you have ymode=log,, you cannot have ymin=0, and ymode=log, is not a valid key after error bars/.cd,. BTW, if you use the code from the answer of your previous question, please consider accepting the answer by clicking on the check mark left of it. — , Dec 01 '19 at 00:05
BTW, your problem can be solved with with either axis discontinuities (see section 4.9.12 Axis Discontinuities) and/or user transformations (see section 4.21 Symbolic Coordinates and User Transformations). — , Dec 01 '19 at 00:07

Please note also that your code has errors and that one exchanges codes on this site via minimal working examples. Also, if one decides to use a code that one has gotten from an answer, one should at least indicate the source, and consider to accept the answer if it solved the problem posed in the corresponding question.

Thank you! I have been looking at the code but I haven't figured out how you solve the scale of the purple bars. I mean, I have another plot similar to this one but the longest bar is around 9000 and the shortest around 1000. So I am trying by changing ticks and scale as you did but without success. Could you please explain me? — Jhonnatan Rodriguez, Dec 02 '19 at 12:59
@JhonnatanRodriguez The trick is to use yscale=0.5 for the purple bars. Of course, the scale factor depends on the problem, but here 0.5 looks fine IMHO. — , Dec 02 '19 at 15:04
