Tracking community B60R in consecutive 5-year time windows, mapping to the previous year. The x-axis indicates years from 1980 to 2013, and the y-axis indicates the nodes, i.e. IPC subclasses, ordered in IPC index. The community mapping is based on consecutive 5-year windows. In each time window, the initial year’s community containing the central node set represented by B60R is shown in blue. In the rest 4 years, colored nodes represent the mapping communities: red indicates the node does not exist in the reference community (community of the previous year), and purple indicates the overlapping part
