此问题是this问题的延伸。
我正在Shiny中绘制一个相当大的gglot。
使用renderPlot(width = 1500, height = 1000, ...
我能够展示整个情节;但是,我现在右边有一个滚动条。我想在fluidRow中扩展列的高度,而不是使用此滚动条。
根据我的理解,Shiny(aka bootstrap)应该动态调整fluidRow的高度,使其与绘图的大小无关。为什么我的可见区域这么小?滚动条很不错,但我希望整个情节都可见。
UI.R
source("helper.R")
shinyUI(fluidPage(theme='test.css',
fluidRow(
column(2,
fluidRow(
h3("Select Customer:"),
wellPanel(class="info", numericInput(inputId="num", label="Select ID:", value=NaN),
if(show_age_slider=='Yes'){textOutput("")},
if(show_edu_slider=='Yes'){textOutput("")},
if(show_gender_buttons=='Yes'){textOutput("")}
))),
#do.call will call the navbarPage function with the arguments in the tabs list
shinyUI(fluidRow(
column(12,
"",
do.call(navbarPage,tabs)
))))))

答案 0 :(得分:6)
您没有发布theme.css
,但问题可能是overflow
参数设置为scroll
,div
持有您应用中的地块CSS。如果div对于其内容来说太小,则会强制滚动条。
height
的默认plotOutput
设置为400px,因此如果您将高度设置为1000,则在renderPlot
中如果设置了div的溢出,则会获得滚动条滚动。
尝试将plotOutput
的高度参数设置为1000px或更高,例如:
#add all the tabPanels to the list
for (i in 2:(number_of_tabPages+1)){
tabs[[i]]=tabPanel(paste0("Tab",i-1),plotOutput(paste0("plot",i-1),height="1100px"))
}
应该给出这样的东西:
您还可以尝试查找为此div设置overflow
到scroll
的内容。我只是怀疑这一点,因为当代码在没有theme.css
的情况下运行时,它看起来很好而不会改变您的代码。
