partial_bundle: Use a partial bundle of plotly.js

Description Usage Arguments Details Author(s) Examples

View source: R/partial_bundles.R

Description

Leveraging plotly.js' partial bundles can lead to smaller file sizes and faster rendering. The full list of available bundles, and the trace types that they support, are available here

Usage

1
partial_bundle(p, type = "auto", local = TRUE, minified = TRUE)

Arguments

p

a plotly object.

type

name of the (partial) bundle. The default, 'auto', attempts to find the smallest single bundle that can render p. If no single partial bundle can render p, then the full bundle is used.

local

whether or not to download the partial bundle so that it can be viewed later without an internet connection.

minified

whether or not to use a minified js file (non-minified file can be useful for debugging plotly.js)

Details

WARNING: use this function with caution when rendering multiple plotly graphs on a single website. That's because, if multiple plotly.js bundles are used, the most recent bundle will override the other bundles. See the examples section for an example.

# ----------------------------------------------------------------------
# This function is always safe to use when rendering a single 
# plotly graph. In this case, we get a 3x file reduction.
# ----------------------------------------------------------------------

## Not run: 
library(plotly)
p <- plot_ly(x = 1:10, y = 1:10) %>% add_markers()
save_widget <- function(p, f) {
  owd <- setwd(dirname(f))
  on.exit(setwd(owd))
  htmlwidgets::saveWidget(p, f)
  mb <- round(file.info(f)$size / 1e6, 3)
  message("File is: ", mb," MB")
}
f1 <- tempfile(fileext = ".html")
f2 <- tempfile(fileext = ".html")
save_widget(p, f1)
save_widget(partial_bundle(p), f2)

# ----------------------------------------------------------------------
# But, since plotly.js bundles override one another, 
# be careful when putting multiple graphs in a larger document!
# Note how the surface (part of the gl3d bundle) renders, but the 
# heatmap (part of the cartesian bundle) doesn't...
# ----------------------------------------------------------------------

library(htmltools)
p1 <- plot_ly(z = ~volcano) %>% 
  add_heatmap() %>%
  partial_bundle()
p2 <- plot_ly(z = ~volcano) %>% 
  add_surface() %>%
  partial_bundle()
browsable(tagList(p1, p2))
