摘要

Complex inter-relationship between financial products plays an important part in financial market analysis; visualization approaches may help in identifying profitable patterns such as price comovement or trend spreading; this paper proposes and implements an animated approach to describe the correlation matrix of stock shares: first, correlation coefficient matrix series are calculated using sliding time window; then thermal diagrams are created and composed into animation movie. Example calculations are carried out using China A-shares of some Zhejiang companies, and resulting animations are presented.
