Render a datatable after clicking on sections of multiple pie charts

Time：11-26

The following app opens up a dataframe which displays data related to the section of pie chart on which you click. This app works only on one pie chart at the moment but i want it to work on multiple pie charts. Is there any way to do it?

library(shiny)
library(plotly)

df <- structure(list(V1 = c("PM00FQ01", "PM00GQ01", "PM00KQ02", "PM033Q01", "PM034Q01T", "PM155Q01", "PM155Q02D", "PM155Q03D", "PM155Q04T", "PM192Q01T", "PM273Q01T", "PM305Q01", "PM406Q01",

CodePudding user response：

The following should work as expected. I'm using reactiveValues to switch between the datasets. Please note the use of the source argument.

PS: Please never nest render* functions in observers as you did in your example.
