Hover does not work with mulitiple wordclouds.

[jahagirdar]

Example http://data.dyumnin.com/analysis/tweeplytics/ashutosh83B.html
This page has 4 wordclouds, If we mouse over the words on any of the wordclouds the rectangular frame and word count appears over the first cloud instead of the cloud over which the mouse is positioned.

Would you happen to have the code used to make this? I see what you're describing in the link, but I'm unable to reproduce it with multiple wordclouds on my own

[jahagirdar]

Can you try with this https://github.com/DataDrivenPolicy/twitteralytics/blob/master/src/twitter_profiles.Rmd

[AdeelK93]

Do you have the other associated files with this Rmd? Some of the required csv's don't seem to be included. Or better yet, would you happen to have a more minimal example?

Below is a minimal example of the hover bug. The 2 wordclouds in the fluidRow exhibit the bug (ie the hover info works fine for "my_wc" but the hover info for "my_wc2" is displayed on top of "my_wc"). The 2 wordclouds placed directly into fluidPage have no issues with the hover information.

library(shiny)
library(wordcloud2)
shinyApp(
  ui=shinyUI(fluidPage(
    fluidRow(
      column(width=6,align="center", wordcloud2Output("my_wc")),
      column(width=6,align="center", wordcloud2Output("my_wc2"))
    ),
    wordcloud2Output("my_wc3"),
    wordcloud2Output("my_wc4")
  )),
  server=shinyServer(function(input,output,session){
    output$my_wc  = renderWordcloud2(wordcloud2(demoFreq))
    output$my_wc2 = renderWordcloud2(wordcloud2(demoFreq))
    output$my_wc3 = renderWordcloud2(wordcloud2(demoFreq))
    output$my_wc4 = renderWordcloud2(wordcloud2(demoFreq))
  })
)

ezpz #32

That look alright to you @AdamSpannbauer?

[AdamSpannbauer]

That seems to be fix the issue on my end. Thanks @AdeelK93

Tested on linux box w/R 3.4.1 & windows box w/R 3.4.2 using Chrome for browser.

I am still confused about this issue, especially in a shiny module.
I create a shiny module to implement wordcloud2, and I call this module itself inside the module to create a modal(pop up window). The hover text does not work(just like http://data.dyumnin.com/analysis/tweeplytics/ashutosh83B.html)

I only give the abstract of my code, since it has 800 lines for one module. You donot want to read it.
namesapce might be the problem for this issue.

I only can use CARN version. So, I do not if #32can solve this problem or not.

##################################################################
\# UI
##################################################################
keywordWordcloudInput <- function( id, title = "Keywords"){
   ......
   ......
}

########################################################################
\# Server
#######################################################################
keywordWordcloud <- function( input,  output, session,data.keywords){
    ....
    ....
    #
    # Full screen modal
    # 
    modalUI <- function(){
      # Use namespace provided by session
      ns <- session$ns
    
      # UI content
      modalDialog({ 
            .......
            # Body
            fluidRow(
                 keywordWordcloudInput(
                 id = ns("keywordWordclouf_fullscreen")
            )#fluidRow
       })#modalDialog
     }#modalUI

     callModule(
        keywordWordcloud,
        id = "keywordWordclouf_fullscreen",
        reactive(data.keywords()),
        fullscreen_link = FALSE
      )#callModule

}

Do you still have the issue if you install #32 ?

[duocang]

sorry to mention, i can not install developer version. i will change my question. I really like wordclod2, but if I can not slove the issue in CRAN version then i have to give it up. Thank you.

If it does fix your issue I hope that it can serve as more motivation for @Lchiffon to merge the PR. I'm also prevented from using wordcloud2 until a fix for the issue is on CRAN.

[duocang]

I just checked, wordcloud2 was updated on 3rd Jan 2018. So I assume it has been fixed. I will check it at work tomorrow and let you guys know.

The updated version on CRAN might fix your issue.

For the issue of hover with multiple wordclouds it made the issue worse. The minimal example posted earlier in this thread only plots 1 of the 4 wordclouds with the version 0.2.1 on CRAN.

@wangxuesong29 Try using this version of wordcloud2: https://github.com/AdeelK93/wordcloud2

The CRAN version does not include #32
