Abstract

The invention discloses a method and device for generating an event group evolution diagram and solves the technical problem of high time complexity in operating an algorithm for configuring event evolution diagrams. The method includes: acquiring one event evolution diagram which represents corresponding relationship between duration and attention hotness of events; acquiring an available area unoccupied by other event evolution diagrams from candidate areas corresponding to the duration according to a segment tree; configuring the event evolution diagram in the available area so as to generate the event group evolution diagram. By the method and device, time complexity in operating the algorithm for configuring the event evolution diagrams is lowered.

Description

Technical field [0001] This application relates to the field of data processing technology, and specifically to a method and device for generating an event group evolution graph. Background technique [0002] At present, in the industry, a line chart is used to graphically display the evolution of event groups. figure 1 A schematic illustration of a line chart in the prior art is shown. Such as figure 1 As shown, the horizontal axis of the line graph can represent time, and the vertical axis can represent the degree of interest in the event. Different colored polylines represent events of different categories, and the number of events of the corresponding type corresponding to the corresponding time point can be displayed at the inflection point of the polyline. in figure 1 In the fold lines of different thicknesses are used to represent the fold lines of different colors. [0003] In academia, bubble charts are used to graphically display the evolution of event groups. figure 2...
