 The high complexity of time-series data makes it difficult for analysts to manually explore and find patterns, leading to an increasing need for visualization techniques to aid analysis in order to extract and communicate insights from event sequence datasets.

 ## Introduction
 
 In social media, behavior monitoring, and other scenarios, it is often necessary to display different behaviors of different users at different times in the form of nodes and edges in linear time evolution. In order to better discover users' behavior preferences, it is also necessary to display behavior statistical information in the form of bar charts. The sequence chart based on linear time mapping can display data in this scenario.
