geom_segment_interactive: Create interactive line segments and curves

In ggiraph: Make 'ggplot2' Graphics Interactive

Create interactive line segments and curves

Description

The geometries are based on geom_segment() and geom_curve(). See the documentation for those functions for more details.

Usage

geom_curve_interactive(...)

geom_segment_interactive(...)

Arguments

...	arguments passed to base function, plus any of the interactive_parameters.

Details for interactive geom functions

The interactive parameters can be supplied with two ways:

• As aesthetics with the mapping argument (via aes()). In this way they can be mapped to data columns and apply to a set of geometries.

• As plain arguments into the geom_*_interactive function. In this way they can be set to a scalar value.
