R: Create interactive histograms and frequency polygons

geom_freqpoly_interactive {ggiraph} | R Documentation

## Create interactive histograms and frequency polygons

### Description

The geometries are based on `geom_histogram()` and `geom_freqpoly()`. See the documentation for those functions for more details.

This interactive version is only providing a single tooltip per group of data (same for `data_id`). It means it is only possible to associate a single tooltip to a set of bins.

### Usage

    geom_freqpoly_interactive(...)

    geom_histogram_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. In this way they can be set to a scalar value.

`girafe()`

### Examples

    # add interactive histogram -------
    library(ggplot2)
    library(ggiraph)

    p <- ggplot(diamonds, aes(carat)) +
      geom_histogram_interactive(bins=30, aes(tooltip = ..count..,
                                 data_id = carat) )
    x <- girafe(ggobj = p)
    if( interactive() ) print(x)

    p <- ggplot(diamonds, aes(price, colour = cut, tooltip = cut, data_id = cut)) +
      geom_freqpoly_interactive(binwidth = 500)
    x <- girafe(ggobj = p)
    x <- girafe_options(x = x,
                        opts_hover(css = "stroke-width:3px;") )
    if( interactive() ) print(x)
