Description Usage Arguments Details Value Author(s) Examples
The function creates a dot plot showing positive and (or) negative event years from a list
of the type as produced by pointer.norm
or pointer.rgc
.

start.yr = NULL, end.yr = NULL,
x.tick.major = 10, x.tick.minor = 5)

The function makes a dot plot showing event years for individual trees. Positive and negative event 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 event years.
Dot plot.

## Plot negative event years from pointer.norm output (method "Neuwirth")
