Questionns about how to set shiny minichart
library(shiny)
library(shinydashboard)
library(DT)
library(leaflet)
source("global.R")
ui <- dashboardPage(skin = "green",
dashboardHeader(title = 'xxx'),
dashboardBody(
tabItems(
# Second content
tabItem(tabName = "list",
column(width = 9, box(width = NULL, solidHeader = TRUE, leafletOutput("map", height = 850))),
column(width = 3, box(width = NULL, selectInput("type", "select", choices = c("normal","monitor"))))
)
)))
server <- function(input, output) {
# Initialization map
output$map <- renderLeaflet({map %>%
addMinicharts(cems$longitude, cems$latitude, type = 'bar',layerId = cems$towncode)})
# Update charts each time input value changes
observe({
cf_data <- switch(input$type, "normal" = Filter(Negate(is.null), cems$factory),"monitor" = Filter(Negate(is.null), cems$cems))
leafletProxy("map") %>%
updateMinicharts(layerId = cems$towncode, chartdata = cf_data, type = 'bar', colorPalette = colors)
})
}
shinyApp(ui, server)
I'm a novice at shiny. I'm using minichart to show my map. But I am disturbed by three problems.
1. The number on the map always show two set of data. But I only want one set when I select one (cems or factory).
2. I have a lot of null in sets. I want to remove them on the map. I have added "Filter". But it doesn't work.
3. I want to show the base map on the dashboard first. But the conde on tutorial shows chart in the beginning.
And I don't know how to revise it.
Can someone give me some advice on the problems? Thanks
