geom_path_interactive

draw interactive paths

The path_interactive geom is used to create interactive lines, tooltips can be displayed when mouse is over lines, on click actions can be set with javascript instructions.

Usage

geom_path_interactive(mapping = NULL, data = NULL, stat = "identity", position = "identity", lineend = "butt", linejoin = "round", linemitre = 1, na.rm = FALSE, arrow = NULL, show.legend = NA, inherit.aes = TRUE, ...)
geom_line_interactive(mapping = NULL, data = NULL, stat = "identity", position = "identity", na.rm = FALSE, show.legend = NA, inherit.aes = TRUE, ...)
