The gear up of journals have been ranked according to their SJR and divided into four equal groups, four quartiles. Q1 (light-green) comprises the quarter of the journals with the highest values, Q2 (yellow) the second highest values, Q3 (orangish) the third highest values and Q4 (cherry) the lowest values.

The SJR is a size-independent prestige indicator that ranks journals by their 'boilerplate prestige per article'. Information technology is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the boilerplate article in a journal, it expresses how central to the global scientific give-and-take an boilerplate article of the journal is.

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 chart shows the evolution of the boilerplate number of times documents published in a periodical in the past 2, three and four years have been cited in the current twelvemonth. The two years line is equivalent to journal touch on factor ™ (Thomson Reuters) metric.
