Question

我有一个情节，我在一个盒子里显示，我想修改盒子的大小，但是情节大于盒子。如何修改它们，以便绘图保持并适合盒子？

#in ui.r
 box(
                  title = "Veniturile si cheltuielile",
                  status = "primary",
                  solidHeader = TRUE,
                  collapsible = TRUE,
                  plotOutput("ven_vs_chelt")
                )




#in server.r
 output$ven_vs_chelt <- renderPlot({
    ggplot(ven_ch, aes(x=ven_ch$ani_tot, y=ven_chelt, fill=tip)) +
      geom_bar(stat="identity", position=position_dodge(), colour="black") +
      xlab("An") + ylab("Valoare venituri si cheltuieli(lei)") +
      scale_fill_manual(values=c("#F78181", "#81F79F"))
  })

您可以修改绘图的大小。这样它就适合盒子。您可以这样做来修改绘图大小：

## In your ui, set the width to 100% in your plotOutput
 plotOutput(outputId = "ven_vs_chelt",  width = "100%")

## In your server, you specify height and width to make a plot fit in your box. You should play with height and width. So that it would fit in the box.
output$ven_vs_chelt <- renderPlot({
ggplot(ven_ch, aes(x=ven_ch$ani_tot, y=ven_chelt, fill=tip)) +
  geom_bar(stat="identity", position=position_dodge(), colour="black") +
  xlab("An") + ylab("Valoare venituri si cheltuieli(lei)") +
  scale_fill_manual(values=c("#F78181", "#81F79F"))
}, height = 300, width = 450)
