I have the following figure.
As you can see the breaklines for the x scale (which is scaled discrete in this case) go right through the different bars. I want to these breaklines to form "lanes" in which the bars are nicely fitted. So instead of having my breaks go through the bar, I would like them to lie at the edge of each bar.
I experimented a lot with the scale_x_discrete function but just can't seem to figure out how to achieve this...
