Problems solved by technology

[0005] In view of the fact that the existing spiral graph visualization method will cause visual clutter due to the intersection of spiral lines when displaying a large amount of data, the present invention provides a spiral graph curve binding method that draws data in the same time interval into bundles ——Spiral graph visualization curve binding method based on time interval

[0055]

[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 invention discloses a spiral figure visual curve binding method based on the time interval. The method includes the steps of firstly, inputting a data set; secondly, drawing concentric state ringsto represent state sets; thirdly, dividing subintervals of the state rings; fourthly, mapping and dividing the types of all data in the data set; fifthly, setting a virtual binding ring; sixthly, drawing a binding curve. The visual disorder degree generated when a large amount of data is displayed through a traditional spiral figure visual method is effectively reduced, a visual interface is moreneat and clear, and the function of more visually knowing and analyzing the data is provided for a user.

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...
