boxplot的细节

The box boundaries and the middle thick line represent the 25th percentile, the 75th percnetile and the median of the data points. The upper and lower lines indicate the largest or the smallest value within 1.5 * box height from the 75th or the 25th percentile. The values outside these two lines are regarded as outliers, indicated by individual circles.
