ggiraph (version 0.7.0)

geom_rect_interactive: Create interactive rectangles

Description

These geometries are based on geom_rect and geom_tile. See the documentation for those functions for more details.

Usage

geom_rect_interactive(...)

geom_tile_interactive(...)

Arguments

...

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

Details for geom_*_interactive 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 (see layer). In this way they can be set to a scalar value.
