This is the most basic parallel coordinates chart you can build with
R, the ggally packages and its
ggparcoord() function.
The input dataset must be a data frame with several numeric
variables, each being used as a vertical axis on the chart. Columns
number of these variables are specified in the columns
argument of the function.
Note: here, a categoric variable is used to color lines, as
specified in the groupColumn variable.
# Library
library(GGally)
# Data set is provided by R natively
data <- iris
# Plot
ggparcoord(data,
columns = 1:4, groupColumn = 5
) + theme_bw()
