Distribution of flare occurrence percentages with effective temperature in Sample 1 and Sample 2. In each panel, blue dots represent the effective temperature and flare occurrence percentage for each star. We overlaid box-and-whiskers plots on each scatter plot to reflect the trend of the scatter plot. In the left four panels corresponding to Sample 1 classifications, the flare occurrence percentage decreases with increasing effective temperature. Similarly, in the right four panels corresponding to Sample 2, except for the single star classification, where the trend observed in Sample 1 is not evident due to a smaller sample size, the other classifications exhibit the same pattern: the flare occurrence percentage decreases with increasing effective temperature.
