DTSg (version 2.0.0)

plot.DTSg: Plot time series data

Description

Displays an interactive plot of a DTSg object. This method requires dygraphs and RColorBrewer to be installed. Its main purpose is not to make pretty plots, but rather to offer a possibility to interactively explore time series data. The title of the plot and the label of its primary axis are automatically generated from the object's metadata (fields). See DTSg for further information.

Usage

# S3 method for DTSg
plot(
  x,
  from = first(self$values(reference = TRUE)[[".dateTime"]]),
  to = last(self$values(reference = TRUE)[[".dateTime"]]),
  cols = self$cols(class = "numeric"),
  secAxisCols = NULL,
  secAxisLabel = "",
  ...
)

Value

Returns a DTSg object.

Arguments

x

A DTSg object (S3 method only).

from

A POSIXct timestamp in the same time zone as the time series or a character string coercible to one. The data is plotted from this timestamp on.

to

A POSIXct timestamp in the same time zone as the time series or a character string coercible to one. The data is plotted up to this timestamp.

cols

A character vector specifying the columns whose values shall be plotted. Another possibility is a character string containing either comma separated column names, for example, "x,y,z", or the start and end column separated by a colon, for example, "x:z".

secAxisCols

An optional character vector specifying the columns whose values shall be plotted on a secondary axis. Another possibility is a character string containing either comma separated column names, for example, "x,y,z", or the start and end column separated by a colon, for example, "x:z". Must be a subset of cols.

secAxisLabel

A character string specifying the label of the optional secondary axis.

...

Not used (S3 method only).

Examples

# new DTSg object
x <- DTSg$new(values = flow)

# plot data
if (requireNamespace("dygraphs", quietly = TRUE) &&
    requireNamespace("RColorBrewer", quietly = TRUE)) {
  ## R6 method
  x$plot()

  ## S3 method
  plot(x = x)
