[0056] The specific implementation steps are as follows:

[0057] Step 1: Enter a periodical time series dataset. Dataset D = {d 1 , d 2 ,...,d n}, where n is the amount of data; d i =(sd i ,sd i+1 , lines i )(1≤ii and sd i+1 Respectively represent the descriptive data of state i and i+1, such as state name; lines i Represents the path data from state i to state i+1; lines i = here f i Indicates the number of paths from state i to state i+1; l i,j Including two time attributes startTime and arriveTime, wherein startTime represents the start time of transition from state i to state i+1, and arriveTime represents the end time of transition from state i to state i+1; l i,j It also includes a time-consuming attribute timeValue, and timeValue represents the time it takes to transition from state i to state i+1. ...

Abstract

The present invention discloses a spiral graph visualization curve binding method based on time intervals, comprising: 1) inputting a data set; 2) drawing concentric state rings to represent the state sets; 3) dividing the sub-intervals of the state rings; 4) ) mapping and dividing the categories of all data in the data set; 5) setting the virtual binding ring; 6) drawing the binding curve and other steps. The invention effectively reduces the degree of visual clutter produced by the traditional spiral diagram visualization method when displaying a large amount of data, makes the visualization interface more neat and clear, and provides users with the function of understanding and analyzing data more intuitively.

Description

technical field [0001] The invention relates to the field of data visualization, in particular to a time-interval-based spiral graph visualization curve binding method. Background technique [0002] In the Internet age, the speed of data generation and dissemination is getting faster and faster, and there are more and more data forms. In the era of big data, phased time series data is a common data type in people's production and life. It contains multiple state transitions, and there are multiple pieces of data between each two state transitions. Each piece of data Both have a time attribute. Many researchers hope to obtain the pattern of data changing over time from periodical time series data, but it is difficult to quickly obtain effective information and knowledge from it through naked eye observation. [0003] In recent years, visualization technology has developed rapidly. Visualization technology aims to help people understand obscure data by abstracting data into...
