Plotting dataset A then adding a lnked X layer with the appropiate button works fine. Rescaling affects both graphs correctly.
Now try adding an axis break (eg between 12 and 13). Add the linked x axis and the data are misplotted - because there is no axis break for the 2nd layer!
you have to add the x axis break manually. The problem then is that only the layer.x.from and layer.x.to values are linked (changing these values affects both graphs). If the axis break is altered for layer 1 then this is not altered for layer 2.
So linking does not seem to apply to the axis breaks!
