Hunter-diagram of all stars shown in Fig. 7. The surface nitrogen abundance is plotted as a function of the projected surface rotational velocity for stars located in the LMC. Upper limits to the surface nitrogen abundance are marked by filled symbols. In addition there is a differentiation between single stars (circles) and probable binaries (triangles). A subdivision into five boxes as defined in Brott et al. (2011b) has been done to simplify the analysis. The green dotted line represents the initial surface nitrogen abundance for LMC B stars.
