This function plots the timeline of the fires and the noise points.

Usage

plot_timeline(
  result,
  from = NULL,
  to = NULL,
  mainBreak = NULL,
  minorBreak = NULL,
  dateLabel = NULL
)

Arguments

result

spotoroo object. A result of a call to hotspot_cluster().

from

OPTIONAL. Date/Datetime/Numeric. Start time. The data type needs to be the same as the provided observed time.

to

OPTIONAL. Date/Datetime/Numeric. End time. The data type needs to be the same as the provided observed time.

mainBreak

OPTIONAL. Character/Numeric. A string/value giving the difference between major breaks. If the observed time is in date/datetime format, this value will be passed to ggplot2::scale_x_date() or ggplot2::scale_x_datetime() as date_breaks.

minorBreak

OPTIONAL. Character/Numeric. A string/value giving the difference between minor breaks. If the observed time is in date/datetime format, this value will be passed to ggplot2::scale_x_date() or ggplot2::scale_x_datetime() as date_minor_breaks.

dateLabel

OPTIONAL. Character. A string giving the formatting specification for the labels. If the observed time is in date/datetime format, this value will be passed to ggplot2::scale_x_date() or ggplot2::scale_x_datetime() as date_labels. Unavailable if the observed time is in numeric format.

Value

A ggplot object. The plot of the timeline.
