is there a way to set the length of the discontinuity in the x axis?
Here is the code I have used:

documentclass{standalone}
usepackage{pgfplots}
pgfplotsset{compat=newest}
begin{document}
begin{tikzpicture}
begin{axis}[
thick,
black,%Set the color of the main axes and numbers
scale=0.389,
axis lines=left,
xmin=200,
xmax=350,
ymin=0,
ymax=3,
major tick length=1.5pt,
minor tick length=1pt,
tick align = inside,
axis x discontinuity=crunch,
legend cell align={left},
legend style={anchor=north, draw=none},
label style={font=tiny},
tick label style={font=tiny},
]
end{axis}
end{tikzpicture}
end{document}

The figure comes out like, with the discontinuity marker that occupies almost one unit.

I would like to have a shorter discontinuity marker, like the one in the picture below.

Thanks for the help!

This is a possible solution. Whether there is a better solution, I do not know. In

documentclass{standalone}

usepackage{pgfplots}

pgfplotsset{compat=newest}

makeatletter

defpgfplots@drawaxis@lines@preparediscont@for#1{%

        ifnumcsname pgfplots@#1axisdiscontnumendcsname>0

                begingroup

                % this group employs several temporary dimension registers

                % and is therefor scoped:

                letdisstart=pgf@ya

                letdisend=pgf@yb

                disend=csname pgfplots@#1max@regendcsname

                advancedisend by -csname pgfplots@#1min@regendcsname

                disend=csname pgfplots@#1@veclengthendcsnamedisend

                ifcasecsname pgfplots@#1axisdiscontnumendcsnamerelax

                        % has already been checked above.

                or

                        advance disend by -12pt

                or

                        defdiscontstyle{decoration={ticks,segment length=4pt, amplitude=8pt}}%

                        advance disend by -8pt

                fi

                pgfplotscoordmath{#1}{datascaletrafo get params}%

                % if #1max + shift < 0pt  (shift is 0 without the scaling trafo)

                ifdimcsname pgfplots@#1max@regendcsname<-pgfplotsretvalb pt

                        % swap start and end

                        disstart=disend

                        disend=4pt

                else

                        disstart=4pt

                fi

                % carry local computations outside of group:

I changed

defdiscontstyle{decoration={zigzag,segment length=8pt, amplitude=3pt}}%

advance disend by -12pt

which was originally in pgfplots.code.tex

defdiscontstyle{decoration={zigzag,segment length=12pt, amplitude=4pt}}%

advance disend by -16pt

to get
