shiny - 如何将 ggvis 图表约束到 Shiny 的仪表板框和列？

Question

我没有找到任何与我的问题和关键字相符的内容。我无法让 ggvis 图表将自己限制在 Shiny 仪表板的给定区域。示例应用程序 (Windows 7) 显示三个 ggvis 图，每个图都超出各自仪表板框和列的右边框 - 除非窗口非常宽。

想法？

library(shiny)
library(shinydashboard)
library(ggvis)

ui <- dashboardPage(
  dashboardHeader(title = "Basic dashboard"),
  dashboardSidebar(),
  dashboardBody(
    # Boxes need to be put in a row (or column)
    fluidRow(
      box(
          width = 4,
          title = "fred",
          ggvisOutput("plot1")
      ),

      box(
        width = 4,
        title = "george",
        ggvisOutput("plot2")
      ),

      box(
        width = 4,
        title = "harold",
        ggvisOutput("plot3")
      )
    )
  )
)

server <- function(input, output) {
  mtcars %>%
    ggvis(~wt, ~mpg) %>%
    layer_points() %>%
    bind_shiny("plot1")

  mtcars %>%
    ggvis(~cyl, ~mpg) %>%
    layer_points() %>%
    bind_shiny("plot2")

  mtcars %>%
    ggvis(~disp, ~mpg) %>%
    layer_points() %>%
    bind_shiny("plot3")
}

shinyApp(ui, server)

您需要设置选项，说明宽度和高度是自动的。您可以按以下方式执行此操作:

mtcars %>%
    ggvis(~wt, ~mpg) %>%
    layer_points() %>%
    set_options(width = "auto", height = "auto") %>%
    bind_shiny("plot1")
