Use value |
Value that determines the distance of a group: •Biggest - groups is classified if the biggest distance value is within the given distance range. •Median - groups is classified if the median distance value is within the given distance range. •Average - groups is classified if the average distance value is within the given distance range. •Smallest - groups is classified if the smallest distance value is within the given distance range. |
Min distance |
