Evolution of the number of published documents. All types of documents are considered, including citable and non citable documents.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal.

The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.
