Study on visualization mode of time series data of coal safety management

Abstract

In order to explore the optimal visualization display mode of coal safety management time series data, this paper selects 7 visualization graphics to carry out eye movement experiment based on different data dimensions and management task types of time series data, and records 3 eye movement indexes of subjects as experimental data, and uses spss19.0 software for data analysis. The results show that: the line chart shows the best effect during displaying the trend task of multi-dimensional data; the spiral chart shows the best effect during displaying the cycle and cycle task of two-dimensional data; the scatter chart shows the best effect during displaying the numerical point recognition task of two-dimensional data.
