Abstract:Similar historical forecasts (also called analogs) are important references for the forecasters in their routine work. The forecasts are multi-variate data, and it is difficult to determine whether two forecasts are similar. In this study, we propose a radar glyph based visualization system to analyze the similarity of analogs using multiple variables. The radar glyph, nested in a radar chart, can effectively provide the forecasters with the similarity based on different variables, while keeping an overall sim… Show more
