Comprehensive geometrical interpretation of h-type indices

Quantitative evaluation of scientists now has become very important at many aspects in the range of nation, even all over the world. Among the indices used for quantitative evaluation, h-type indicators are the most popular right now. However, because of the problem that mastering more than 40 variants is difficult and time-consuming, we need an intuitional and quick method by which we can present these indicators for evaluators and those even with little knowledge regarding to h-type indicators. In this paper, we introduce the paper-citation histogram in which most h-type indicators could be illustrated with their geometrical interpretation. With the help of these plots, evaluators can better understand the indices in a relatively short time. Meanwhile the geometrical interpretation can provide an insight into the research achievements of scientists.
