Design of Dial-type Spectrum Visualization System

The analysis of stellar spectrogram is an important subject in astronomy nowadays. Many astronomical researches need to analyze, mine and extract information from stellar spectrogram to obtain the physical parameters of celestial bodies. Different from previous stellar spectrogram plotting, this paper proposed a novel form of stellar spectrogram display, examining and analyzing the spectrogram from another perspective, used a new pattern to establish spectral model including Spectral lines by dial chart and provided the ability to search the spectrum of a specified star, which is unique and innovative. Using Mongo database to save tens of thousands of stellar parameters and PYECHARTS to show ring stellar spectrogram. This paper includes the significance of the project, he implementation of algorithm and the realization of functions.
