Same sidebarPanel for different tabs

[DrunkenPhD]

My ui.R file:

shinyUI(fluidPage(theme = shinythemes::shinytheme("lumen"),

                  

  fluidRow(

    column(width = 8, includeMarkdown("intro_data.md")),

    column(width = 4, includeHTML("intro_logo.html"))

  ), 

  sidebarLayout(

    

    sidebarPanel(

      radioButtons('indicator', ...)

      sliderInput("year",....)

      )

      

),

mainPanel(

  tabsetPanel(

    tabPanel( 'Data',    DT::dataTableOutput('ex1') ),

    tabPanel('Graphs',  DT::dataTableOutput('ex2')))

  )

))

))

Now my radioButtons and sliderPanel work fine form tabPanel  Data and the output is OK. I need in tabPanel Graphs to show a  graph based on user inputs in sidebarPanel but it is not working. 

Any ideas?
