Hey i've just started working with R and Shiny. Trying to make a dashboard which displays different charts. As there is a lot of data to process, the plots or charts take some time to display after the action button is clicked i.e. "launch Campaign' Is there anyway i could show a spinning wheel or a loading icon in the white blank space, while this delay takes place? Dashboard with blank space on the right
There is wonderful shinycssloaders
package https://github.com/andrewsali/shinycssloaders which does what you want:
library(shiny)
library(dplyr)
library(shinycssloaders)
ui <- fluidPage(
actionButton("plot","plot"),
plotOutput("Test") %>% withSpinner(color="#0dc5c1")
)
server <- function(input, output, session) {
data <- eventReactive(input$plot,{
rnorm(1:100000)
})
output$Test <- renderPlot({
plot(data())
})
}
shinyApp(ui = ui, server = server)
