Figure 19
The graph is titled “Reference Publication Year Spectroscopy”. The horizontal axis is labeled “Year” and ranges from 1704 to 2023 in increments of 11 years. The vertical axis is labeled “Cited References” and ranges from 0 to 20000 in increments of 10000 units. At the bottom of the graph, a text reads, “Number of Cited References (Black line), Deviation from the 5-Year Median (red line)”. The data from the graph is as follows: The red line begins from (1704, 0) and remains horizontal up to (1968, 0). From this point, it passes through small peaks and sharply rises to (2017, 9,253) and terminates at (2023,0). The black line begins from (1704,0) and remains horizontal up to (1968,0). From this point, it passes through small peaks and rises sharply to (2017, 28,283) and terminates at (2023,0). Note: All the numerical data values are approximated.Reference publication year spectroscopy. Source: Output from RStudio, Biblioshiny
