不在 shinydashboard 的 menusubItems 中显示图表（使用 highcharter）

Question

我连续几个小时都在尝试让它工作，但它不起作用。我只是希望在此仪表板中为不同的选项卡呈现图表。我尝试使用 renderHighchart2 和 highchartOutput2 用 box() 将它封闭起来。图表在外面闪闪发光就好了，有什么问题吗？

编辑：我指的图表是highcharts，而不是valueboxes！此外，该应用程序确实为每个图形和 fluidRow 显示了正确的标题，但是无法绘制 highcharts

这是代码：

       library(shiny)
        library(shinydashboard)
        library(highcharter)
        library(tidyverse)
        
        
        ui <- dashboardPage(
          skin = "purple",
          dashboardHeader(title = h4(HTML("Generic company name<br/>Something to analyze")),
                          titleWidth = 275),
          dashboardSidebar(
            sidebarMenu(
              menuItem("Dashboard",icon = icon("dashboard"),
                       menuSubItem('Samenvatting', tabName = "samenvatting", icon = icon('atlas')),
                       menuSubItem('Statusverloop', tabName = "statusverloop", icon = icon('battery-three-quarters')),
                       menuSubItem('Tijdsverloop', tabName = "tijdsverloop", icon = icon("hourglass-end")),
                       menuSubItem('Affiliates', tabName = "affiliates", icon = icon("handshake")),
                       menuSubItem('Klanten informatie', tabName = "klanteninformatie", icon = icon("address-card"))
              ),

            )
          ),

                      ),
                      fluidRow(
                        column( width = 6,h4("Wekelijkse statistieken", align = 'center'), highchartOutput('a') ),
                        column( width = 6,h4("Wekelijkse totale statistieken", align = 'center'), highchartOutput('b'))

                        column( width = 6,h4("Affiliates over passen", align = 'center'), highchartOutput('b'))
                      )

在 shiny 中，您不能在 UI 中多次引用任何 output。

尝试将图表存储在一个对象中（可以使用 reactiveValues 或 reactive() 来存储它），然后将该对象分配到单独的输出中。
