autoplot.persistence_diagram: Plot for 'persistence_diagram' objects

In rgudhi: An Interface to the GUDHI Library for Topological Data Analysis

Plot for persistence_diagram objects

Description

This function creates a visualization of a persistence diagram and returns the corresponding ggplot2::ggplot object which enable further customization of the plot.

Usage

## S3 method for class 'persistence_diagram'
autoplot(
  object,
  dimension = NULL,
  alpha = 0.6,
  max_intervals = 20000,
  legend = FALSE,
  greyblock = TRUE,
  n = 10L,
  type = c("barcode", "diagram", "density"),
  ...
)

Arguments

object	An object of class persistence_diagram.
dimension	An integer value specifying the homology dimension to visualize. Defaults to NULL in which case the dimension is retrieved directly in the persistence_diagram object.
alpha	A numeric value between 0 and 1 specifying the transparency of points and lines in the plot. Defaults to 0.6.
max_intervals	An integer value specifying the maximal number of intervals to display. Selected intervals are those with the longest lifetime. Set it to 0 to see them all. Defaults 20000L.
legend	A boolean value specifying whether to display the legend about the homology dimension(s). Defaults to FALSE.
greyblock	A boolean value specifying whether to display a grey lower triangle in the diagram representation for nicer output. Defaults to TRUE.
n	An integer value specifying the number of bins for plotting the diagram as a density. Defaults to 10L.
type	A string specifyfing the type of representation. Choices are "barcode", "diagram" or "density". Defaults to "barcode".
...	Other parameters to be passed on to next methods.

Value

A ggplot2::ggplot object.

Examples

pd <- as_persistence_diagram(tibble::tibble(
  birth = 0,
  death = 1,
  dimension = 0
))
ggplot2::autoplot(pd)
