UI for plotly with download data button in modebar

Description

UI for plotly with download data button in modebar

Usage

downloadablePlotlyUI(id, width = "100%", height = "auto", inline = FALSE)

Arguments

id	id string that gets namespaced by shiny::NS.
width, height	Must be a valid CSS unit (like "100%", "400px", "auto") or a number, which will be coerced to a string and have "px" appended. Note that, for height, using "auto" or "100%" generally will not work as expected, because of how height is computed with HTML/CSS.
inline	use an inline (span()) or block container (div()) for the output

Value

an HTML tag object corresponding to the UI for downloadablePlotly.

Examples

library(shiny)
library(shinyjs)
library(shinydlplot)
library(plotly)
ui <- fluidPage(
  useShinyjs(),
  downloadablePlotlyUI(id = 'iris')
)
server <- function(input, output, session) {

  plot <- plot_ly(data = iris, x = ~Sepal.Length, y = ~Petal.Length)

  callModule(downloadablePlotly,
             id = 'iris',
             plot = plot,
             filename = 'iris.csv',
             content = function(file) {write.csv(iris, file)})

UI for plot with download data button

Description

UI for plot with download data button

Usage

downloadablePlotUI(
  id,
  title = "Download plot data",
  width = "100%",
  height = "400px",
  zoom = FALSE
)

Arguments

id	id string that gets namespaced by shiny::NS.
title	Text to display on hover of download button.
width, height	Image width/height. Must be a valid CSS unit (like "100%", "400px", "auto") or a number, which will be coerced to a string and have "px" appended. These two arguments are ignored when inline = TRUE, in which case the width/height of a plot must be specified in renderPlot(). Note that, for height, using "auto" or "100%" generally will not work as expected, because of how height is computed with HTML/CSS.
zoom	if TRUE brush then double-click to zoom.

Value

an HTML tag object corresponding to the UI for downloadablePlot.
