Based on the following dataset, the attached graph visualizes the average, minimum and maximal length of authored articles (measured by the number of pages) in each issue of the Chinese Economic Monthly/Journal between 1924 and 1936, depending on the topic they address. Relying on R package "ggplot2", we alternatively used faceted graph line (1) and boxplots (2) to visualize variations in the length of articles from one topic to the other. The code used for classifying topics is described in the notice attached to the original dataset.
