This work deals with the scattering entropy of quantum graphs in many different circumstances. We first consider the case of the Shannon entropy, and then the R\'enyi and Tsallis entropies, which are more adequate to study distinct quantitative behavior such as entanglement and nonextensive behavior, respectively. We describe many results, associated with different types of quantum graphs in the presence of several vertices, edges and leads. In particular, we emphasize that the results may be used as quantifiers of diversity or nonadditivity, related to the transport in quantum graphs.
