Create Interactive Web Graphics via 'plotly.js'

Easily translate 'ggplot2' graphs to an interactive web-based version and/or create custom web-based visualizations directly from R. Once uploaded to a 'plotly' account, 'plotly' graphs (and the data behind them) can be viewed and modified in a web browser.

Readme

Build Status

plotly

An R package for creating interactive web graphics via the open source JavaScript graphing library plotly.js.

Installation

Install from CRAN:

install.packages("plotly")

Or install the latest development version (on GitHub) via devtools:

devtools::install_github("ropensci/plotly")

Getting Started

Web-based ggplot2 graphics

If you use ggplot2, ggplotly() converts your plots to an interactive, web-based version! It also provides sensible tooltips, which assists decoding of values encoded as visual properties in the plot.

library(plotly)
g <- ggplot(faithful, aes(x = eruptions, y = waiting)) +
  stat_density_2d(aes(fill = ..level..), geom = "polygon") + 
  xlim(1, 6) + ylim(40, 100)
ggplotly(g)

If you'd like to see how ggplotly() does in converting different ggplot2 examples, we host a plotly version of the official ggplot2 documentation. We also have some of our own examples here.

plotly's custom R interface

plotly.js supports some chart types that ggplot2 doesn't (our cheatsheet provides a nice summary of the available chart types). You can create any of these charts via plot_ly().

plot_ly(z = ~volcano, type = "surface")

https://plot.ly/~brnvg/1134

We have a number of vignettes which explain the plot_ly() interface in depth as well as numerous examples on the plotly website and bundled with the package.

Capturing plotly events

plotly.js exposes a number of 'standard' events that work consistently across plot types. It's easy to hook into these events using the event_data() function in shiny apps, as these examples demonstrate:

  1. 2D events (source)
  2. Linked Clicks (source)
  3. Linked Brush (source)

http://104.131.111.111:3838/plotlyLinkedBrush/

You can also hook into these events without shiny using htmlwidgets::onRender() (example). This, however, requires JavaScript knowledge and makes it much harder to coordinate views between htmlwidgets.

We have lots of examples on https://plot.ly/r/ and https://plot.ly/ggplot2/, but a more comprehensive review is also available at https://cpsievert.github.io/plotly_book/
