  In research evaluation of single researchers, the assessment of paper and
journal impact is of interest. High journal impact reflects the ability of
researchers to convince strict reviewers, and high paper impact reflects the
usefulness of papers for future research. In many bibliometric studies, metrics
for journal and paper impact are separately presented. In this paper, we
introduce two graph types, which combine both metrics in a single graph. The
graphs can be used in research evaluation to visualize the performance of
single researchers comprehensively.
