Create an Interactive Parallel Coordinates Plot with plotly

Generates a customizable interactive parallel coordinates plot using plotly, supporting dimension selection, color mapping, and font styling.

Usage

parallelCoordinatesPlot(
  data,
  dimensions,
  color.by = NULL,
  color.scale = "Viridis",
  palette.selection = NULL,
  line.opacity = 0.5,
  line.width = 1,
  show.colorbar = TRUE,
  label.font.size = 12,
  label.font.color = "black",
  label.font.family = "Arial",
  tick.font.size = 10,
  tick.font.color = "black",
  tick.font.family = "Arial",
  title.text = "",
  title.font.size = 16,
  title.font.family = "Arial",
  title.font.color = "black",
  bgcolor = "#FFFFFF"
)

Arguments

data

A data.frame or tibble containing the data to plot.

dimensions

Character vector of column names to use as dimensions (axes). Must contain at least two columns. Non-numeric columns are mapped to integers.

color.by

Optional character, column name to color lines by. Numeric columns use a continuous colorscale (color.scale); categorical columns use a discrete palette (palette.selection) and are displayed with category names on the colorbar. Default: NULL.

color.scale

Character, plotly colorscale name for line coloring when color.by is numeric. Options include "Viridis", "Cividis", "Inferno", "Magma", "Plasma", "Blues", "Greens", "Reds", "Oranges", "RdBu", "RdYlBu", "Spectral", "Jet", "Hot", "Cool", "Portland". Default: "Viridis".

palette.selection

Character vector of hex colors used to color lines when color.by is categorical. May be unnamed (colors applied in order to the sorted unique levels) or named by level. If NULL, the plotly color.scale is used as a fallback. Default: NULL.

line.opacity

Numeric, opacity of lines between 0 and 1. Default: 0.5.

line.width

Numeric, width of lines in pixels. Default: 1.

show.colorbar

Logical, whether to show the colorbar. Default: TRUE.

label.font.size

Numeric, font size for dimension labels. Default: 12.

label.font.color

Character, hex color for dimension labels. Default: "black".

label.font.family

Character, font family for dimension labels. Default: "Arial".

tick.font.size

Numeric, font size for axis tick labels. Default: 10.

tick.font.color

Character, hex color for axis tick labels. Default: "black".

tick.font.family

Character, font family for axis tick labels. Default: "Arial".

title.text

Character, main title text for the plot. Default: "".

title.font.size

Numeric, font size for plot title. Default: 16.

title.font.family

Character, font family for plot title. Default: "Arial".

title.font.color

Character, hex color for plot title text. Default: "black".

bgcolor

Character, hex color for the plot background. Default: "#FFFFFF".

Value

A plotly object representing the interactive parallel coordinates plot.
