The function makes a dot plot showing pointer years for multiple sites. Positive and negative pointer years are indicated with different symbols. If event years were defined using method.thresh "Neuwirth"
(pointer.norm
), different tones of gray indicate weak, strong and extreme pointer years, based on the most common event year class.
Dot plot.
