Gmt psxy broken axis

Hi

I am trying to plot a box-and-whisker plot as per attached. I did it successfully but I can not visualize the variation in my plot due to large maximum values. Therefore I want to plot broken/gapped y-axis. Is there any kind of option available in GMT 6.0.0? or Is there any other option to visualize my variation?
I tried -g option as (-gy5) but it is not working I am sure I am doing some mistake in this.

please provide your suggestion.

j=-JX5i/2i
r=-R0.5/12.5/0/45
x=-Bxa1f1
y=-Bya10f2
gmt psxy $j $r $x $y -BWSne -EY0.4 -G200 -X2 -Y18 > $out1

No, there is no broken/gap axes support in GMT. You would have to script it yourself.
